Integrate Kirby CMS into existing site with MySQL

Hi. I have to add some CMS to existing website with mysql database. I’ve used Kirby before for building websites from scratch and really like it’s admin panel.
I know it sounds strange but is there any chance to use KirbyCMS admin panel for manage mysql data and some assets (images, videos, etc.)?

How much data? If it’s not too much it might be easier to migrate the data into kirby text files instead of trying to make the kirby panel work on mysql.

Otherwise there is this guide here: Content from a database | Kirby CMS

I’ve looked the topic by the link and it seems to be my case. Thanks a lot!
