I have been reading through the MS Teams docs regarding adding an employee app store but I need to know if something is possible. I see if you make a Canvas app you can share it so it can be added to Product Showcase tab. What I want to know is if I can create a link to a custom website, Sharepoint site, etc. as an available "App" a user can see/add to their Teams Product Showcase tab. To our end-users a custom app we make is just an app. They don't care if its first or third party. I just want a tile to show on their screen that will open a browser tab when clicked and let them use our intranet Website app or Sharepoint app.
