Google Account Recovery Stuck - No Access To Gmail

I have a problem accessing my Google account on my Android device because I no longer have access to the old phone number that was registered to the account. When I try to recover my Gmail password, the process directs me to verification methods that rely on that old phone, which I cannot use anymore. Previously, I had also set a secondary password/recovery option on this account, but I am still unable to complete the password reset process and regain access. I have not yet been able to reach Google support directly about this issue. I kindly request that you assist me in verifying my identity through an alternative method and help me regain access to my Gmail account, since I can no longer use the old phone linked to it.
