I've written TG bots in the past (years ago, before I stopped using it for privacy reasons), often for personal/business use. What's nice about it is that you can send yourself notifications with a relatively straightforward bot API and have secondary command interfaces for querying. So you're on the road, you get a notification that some event happened for your business and then you converse with the bot to get more info about what's going on. Before TG I had it in Slack. After TG I tried with a signal bot but that's a terrible SDK. Now I have a bespoke app that I don't use often enough.

Bottom line, anything a TG bot offers can be reproduced on a more secure, more privacy-preserving platform.
