Interestingly, in the latest Telegram Beta for Android, your wallet may appear on your profile even if another user simply opens the «Money» tab to send you Gram. This triggers the creation of your wallet, although its status remains «Inactive».
This means that if someone has opened the «Money» tab to send you Gram at least once, your wallet may already be visible on your profile, even if you haven't activated it yet. You can then find your wallet address yourself without having to wait for someone else to send it to you.
