Can't we do that easily with #LNbits already? I don't remember it to be anything hard.

Yes, it's not that hard - but you need #LNbits hosted somewhere for that. Or an FTP server for 'classic' solution.
With the solution above, you just need free GitHub account.
Yes I figured out after posting, I read too fast first and was thinking you need to deploy some code on a server, not that's all in your Github account directly.
I should give it a try.
