How to Deauthorize or Authorize Adobe Digital Edition on my Macbook

Let me try this way:

I transferred the contents of my old Macbook to a new Macbook.

For some reason my son used Adobe Digital Edition with his Adobe ID.

When I open ADE on my new computer, its authorization appears.

I've already tried to deauthorize the pc, but for some reason it's not possible, despite having the correct session open.

I also tried to install a new version, but my child's ID always appears.

I am currently unable to use my Epub books as I cannot authorize my Adobe ID.

Can you please suggest some solution?
