Magic link on iOS devices (via Telegram etc.)

So I’m alerting users in a Telegram group whenever a new post is published (I have some reasons not to do this via email exclusively), in any case in the Telegram I post something like

A new post is out, [link]you may now read it in your dashboard[/link]. Following that link you’ll open the site with the Telegram built in browser, add your email to log in, then get a magic link. However there is no way to then log in in that Telegram browser (so that next day when the notification hits, users stay logged in).

Is there any way to allow for this to work?

Thanks for any ideas
