Can't sign a document with my digital certificate - TOKEN dont appear to be instaled Adobe Pro 2020

Question

I'm trying to sign documents digitally, but my digital certificate (from Brazil), which is in token format, does not appear in the list, and Adobe does not allow/find it for installation. Adobe Pro 2020 Mac version 2020.005.30516. I have attached screenshots of the error.
Only Adobe Acrobat Pro 2020 does not find the certificate. The adobe reader(version 2023.003.20269)can find it according to the attached image.

Hi @Ricardo Paiva

Thanks for the detailed information.

Please try the following steps to see if it works for the Acrobat:

Restart Adobe Acrobat Pro; sometimes, a simple restart of the application can resolve issues related to certificate recognition.
Check Certificate Store: Verify that the digital certificate is properly installed on your system's keychain or certificate store. If installed correctly, it should be available for use in other applications.
Reinstall Certificate: Try removing the digital certificate from your keychain and then reinstalling it. Ensure that you follow the proper installation process.
Follow the steps suggested in a similar discussion here and change the preferences setting: https://community.adobe.com/t5/acrobat-reader-discussions/the-credential-selected-for-signing-is-invalid-army-cac-mac-os-10-14/m-p/10634727#M55738
