Can't Access Facebook Account, How to Recover?

I recently encountered a serious issue where my Facebook account got hacked, and I'm struggling to regain access. I'm reaching out to see if anyone here can provide a step-by-step guide on the best methods to recover a hacked Facebook account. Here's what happened:

I play the Free Fire game on my Android phone and use my Facebook account to log in. Yesterday, I suddenly found myself unable to log into Free Fire using my Facebook account. My game account is very old and can only be accessed through Facebook, which was no longer working. When I checked my Facebook account, I discovered the same issue: I couldn't access it. I attempted to recover my password using the "Forgot Password" option, but it was to no avail.

Given these circumstances, what should be my first steps to secure my account and regain control? I've heard about reporting the account as compromised and using trusted contacts, but I'm not entirely sure how to go about it.
