Get a burner phone number and set up a pin, problem solved. If you think telegram can be anonymous you are being rather naive. Go to your session lists and read information on all of your connected devices, whether connected through proxy or not. That’s not a one-out example. Did you share contacts list? Did you ever enable location? What about your device’s uptime? It is very much pseudonymous.

Many if not most countries do not allow getting a phone SIM without linking it to your official government ID.
Edit: I rather suggest using XMPP. But Telegram is not strictly worse then Signal in every way.
