Access to invitation

So I was invited to check out an app using Adalo for iOS. The issue is that when I hit the send to button it states that I should save it on my Home Screen, however, that option is not available on my iPhone when I attempt to do it. Can someone please explain how to get this onto my phone? And how come there is no install button? Any help would be greatly appreciated :exploding_head:

On iOS you can install a PWA on home screen only with SAFARI browser.

Ok so pls forgive me but I am not well versed to do it through the browser.

Can you please walk me through it.

Whatever you can do would be greatly appreciated :hushed:
