I do not recommend Telegram for anything. It's not privacy tech, disguised as privacy tech. Telegram's E2EE is not applied by default, an investigation out of Germany concluded that Telegram shares data with governments, though Telegram says it has never happened.

According to their privacy policy Telegram logs user IP addresses and metadata and stores it for up to 12 months. Their privacy policybalso states that upon receiving a court order that "confirms you are a terror suspect" they may disclose your IP and phone number to authorities.

I have witnessed this on twitter during the blm protests, all the far-right anti-protestors were having their telegram convos leaked in almost real time while the BLM protestors were largely using Signal and did not suffer from these Twitter leaks.

I do not trust Telegram's commitment to privacy and security at all.
