Free Fire 7 year old title code

The 7 Year Old Title in Free Fire appears to be a special designation that players are trying to unlock. Based on what I found, there are discussions and videos explaining different methods to obtain it, including adding a specific code to your player bio. Some players suggest using a format like [b]100FFFF]€-5-(7YEAROLD), but it's unclear if this method is officially recognized by Garena.
