PowerApp in Teams; How to get shared link of app to open in Teams or browser to prompt Teams?

Good morning!  

I have added my PowerApp to my Teams channel and have copied and shared the link to the tab/app.  This is copied and pasted, & opened in the browser, but how can I get the browser to prompt to open this link in Teams, as I've seen for meetings?  So, that it takes the user directly to the app in Teams?

When clicking on meetings, it opens in browser, which then I'm prompted: "Open Microsoft Teams? https://teams.microsoft.com wants to open this application.  I know that the prompt includes "launcher/launcher.html".  I've added this to the link URL for the app, and it opens in Teams, however, it does not take the user directly to that tab/app.

How can I do this for the app?  Any information or guidance is greatly appreciated.  Thank you.
