How to add forum as shorcut app in android

One I managed to have created on my 8" android tab an icon that looked like an app that would open directly forum, and even had extra options on the icon shorcut like 8nbix when pressing it couple seconds.

But… don’t recall how i did it, it was really useful since there’s no app in Google Play Store for data vault user group.

I wonder if anyone knows or recalls how to add shorcut like it was an app to forum in our android devices ?

Thanks, Merci, Gracias, Obrigado, ACK-001, True, Ok Uk :pray::sparkles::relaxed:
