Garena Free Fire Gmail Account Lost – Request Access to Original Account

I am an Android phone user and I want to recover my Free Fire account that is connected with Gmail. My Free Fire ID number is 7100859416 and this account belongs to me. I have been using this account for about 4 years. I want to link or recover this Free Fire ID with my Gmail account, but my Free Fire ID does not show as I expect and I cannot access or use it properly. I also do not know or remember the exact Gmail address or name that is connected to this Free Fire account, so I cannot fix the problem by myself. Because of this situation I cannot use my own Free Fire account that I have played on for 4 years. I kindly request support to fully recover my Garena Free Fire account with ID 7100859416, help me identify the Gmail that is linked to it, link it correctly, and give me back full access to my account.
