Fix Telegram Not Sending SMS Code

I am writing regarding a serious problem I am experiencing with my Telegram account, which I can no longer access because I am not receiving the SMS login code. For a while now, every time I try to log in, the application does not send me the SMS verification code needed to enter my account. I am stuck on the login screen and cannot move forward, so I have completely lost access to my account and my conversations. I have not been able to resolve this issue on my own and I have not received any guidance within the app. I kindly request that my phone number be verified and that the SMS login code be sent to me so that I can access my Telegram account again without having to purchase any additional services. I ask for your urgent help in reactivating access to my account as soon as possible.
