Retrieve alarm settings for a telegram bot

Question

I am building a telegram bot that sends a notification about the weather conditions to a user as soon as his/her morning alarm goes off.

I got stuck on the first phase right away: how do I access the time of the alarm on the user's phone? Which algorithms could I use?

I could set the bot to ask the question about the time separately, but accessing it automatically is cooler.

Thank you in advance.
