How to make customization in WordPress customizer?

Question

WordPress

Good day! You need to make the following settings in the customizer:

I need to be able to add my own blocks with settings, like here, and to be able to select a picture and a link in the blocks.
Tell me how can I do this? No matter how much I searched the Internet, I did not find anything.
PS Thanks in advance

Answer 2

And why do it at all in the customizer? It’s possible through ACF and that’s it, you’re creating problems, one setting is small for one page, well, it’s nonsense
