To know if the difficulty of transferring to an options page is complicated, I would have to know your project.
I also thought of another idea. You may also be able to integrate an ACF form into your WordPress admin page with “acf_form()”. Put a look here: https://www.advancedcustomfields.com/resources/acf_form/
(But it’s just one idea among others.)
Just know, you have several possibilities, but I can’t know if what I’m saying is well thought out because I don’t know your project.
