In short, I am trying to press the "NEXT" button in this image. Its corresponding HTML is highlighted in the Elements tab on the right. It's a button. However, the entire frame is somehow not searchable easily. I tried pressing it in many ways such as:
driver.find_element_by_css_selector('button.page_btn_font.btnNextNormal.ng-binding').click()
I tried a lot more but nothing worked. So I went to one of the suggested questions when I tried posting this question and tried to list all the buttons in the page. Surprisingly, I only found, and could click, the two buttons in the upper header on the right: Tools and JOHN DOE. In short, I cannot even access the frame below with all the buttons.
I have checked the top of the HTML code and also posted a snippet of it below the main picture. The entire frame is highlighted when I hover over the second div with id='content-container" so I somehow have to get into that. Keep in mind the button itself is 10-15 layers deep into divs so going in order will not be easy if we go that route.
Please see the picture at full zoom.

I think the problem is not really in the part I showed. That's the button I want to click. But the problem is bigger than thatthis really makes sense
