How to simplify a javascript function into clean readable code?

here i have created a function , it is framing a object by getting two values as arguments. It is working fine. But in the code wise is not simple. It is not readable. Here i am sharing the code of what i have done. Please suggest me where i have to modify the code. In order to make it more clear and readable.

import uuid from 'uuid/v4';

const questionsObject = {};
const finalDndDataFormat = {};

let value = [{"groups":[{"notes":"","questions":[{"name":"loanAmount"}]},{"questions":[{"name":"loanReason"}]},{"questions":[{"name":"email","type":"email"}]},{"questions":[{"name":"title","required":true}]},{"questions":[{"name":"firstName"},{"name":"lastName"}]}],"id":"my-needs"},{"groups":[{"questions":[{"name":"phone"},{"name":"isCellPhone"}]},{"questions":[{"name":"dateOfBirth","options":[]}]},{"questions":[{"name":"residenceStatus","options":[],"label":"q_ownRent_text","type":"radio","required":true}]},{"questions":[{"name":"addressLine1"},{"name":"addressLine2"},{"name":"city"},{"name":"province","options":[]},{"name":"postalCode"}],"title":"q2_supporting_2"},{"questions":[{"name":"employmentStatus","options":[]}]}],"id":"a-bit-about-me"},{"groups":[{"questions":[{"name":"residenceDuration","options":[]}]},{"questions":[{"name":"previousAddressLine1"},{"name":"previousAddressLine2"},{"name":"previousCity"},{"name":"previousProvince"},{"name":"previousPostalCode"}],"title":"q2_supporting_2"},{"questions":[{"name":"previousResidenceDuration"}]},{"questions":[{"name":"residenceStatus"}]},{"questions":[{"name":"principalResidence"}]},{"questions":[{"name":"residenceType"}]},{"questions":[{"name":"propertyValue"}]},{"questions":[{"name":"monthlyMortgagePayments"}]},{"questions":[{"name":"mortgageBalance"}]}],"id":"my-home"},{"groups":[{"questions":[{"name":"employmentDuration"}]},{"questions":[{"name":"previousEmploymentDuration"}]},{"questions":[{"name":"paycheckAmount"}]},{"questions":[{"name":"paycheckFrequency"}]},{"questions":[{"name":"hasAdditionalIncome"},{"name":"additionalIncomeSource"}]},{"questions":[{"name":"hasChildTaxCredit"},{"name":"childTaxCreditMonthlyAmount"},{"name":"numberOfDependentsChildTaxCredit"}]},{"questions":[{"name":"sinNumber"}]}],"id":"my-income"},{"groups":[{"questions":[{"name":"hasPaydayLoan","options":[]},{"name":"paydayLoanAmountOwing"}]},{"questions":[{"name":"hasOtherLiabilities","options":[]},{"name":"otherLiabilitySource","options":[]}]},{"questions":[{"name":"isEasyHomeCustomer","options":[]},{"name":"easyhomePaymentsLiabilityMonthlyAmount"}]}],"id":"liabilities"},{"groups":[{"notes":"","questions":[{"name":"agreeTermsConditionsAndPrivacyPolicy","options":[],"links":[]}]}],"id":"t-and-c"}]
let appPages = ["my-needs", "a-bit-about-me", "my-home", "my-income", "liabilities", "t-and-c"]

const setDndDataStructure = (value, appPages) => {
 
    const dndFormat = value?.map((data) => {
        appPages.forEach((pages) => {
            switch (data?.id) {
                case pages:
                    const questions = data?.groups || {};
                    questions.map((obj) => {
                        obj.id = uuid();
                        const uniqueQuestionName = obj?.questions?.map((questionsField) => questionsField?.name);
                        obj.unique = uniqueQuestionName[0];
                    });
                    const dndDataFormat = { [pages]: { name: pages, items: questions } };
                    Object.assign(questionsObject, dndDataFormat);
                    Object.assign(finalDndDataFormat, questionsObject);
                    break;
                default:
                    break;
            }
        });
    });
    return finalDndDataFormat;
};

setDndDataStructure( value , appPages )

Result:
