Hi , try this solution, it has worked for me on S24, location of the menu might be different
From Contact click on the triple line on the left.
Select Contact Settings
Ignore the first show 3rd party options. Below this should be the About Contact.
Select About Contacts
Click on the word Contacts should give you a note x step from before entering hidden options.
Once you click 9 times you should be in 3rd party accounts visibility.
Enable the appropriate app.
