Hi Mario,
I just Googled the topic and used the info from this site: http://davidgiard.com/2019/01/27/AddingAWebsiteTabToAMicrosoftTeamsChannel.aspx
For the URL to use, I navigate to the project in the Clarity modern UX, then copy the address for pasting into Teams.
Regards,
Dale
Thank you, Suman. Will pass this to our app support team and give it a try.
