Echogram - TV for Telegram

@Ro1li Lior, please help me. My Telegram account was disconnected from my PC, and I no longer have access to the phone number registered to the account. The only device where I can still access something from the account is my TV, through Echogram, where I might be able to see the access code sent by Telegram. This account has all my movie groups, including paid groups, and I really need to recover access on my PC. Is there any safe way to view the login code or access the messages received by Telegram through Echogram? This seems to be my only option at the moment.
