Does the extension work ???
{DISCLAIMER} I know it's war in Ukraine and that you might have better things to do. So it's ok if you don't have time and energy to work on it.
As an admin I updated to version6.3.0 on CiviCRM 5.67.3 (WP) with the Rest Api extension add-on also installed. On the backoffice, I can see that my settings are ok but I can't connect if I uncheck the 'Show Public area' checkbox and if I check it then I just have access to petitions. I've controlled all my settings and just can't succeed to make it work properly to access contacts and activities. Is there an updated documentation maybe?
