i'm using geyser and can't figure out something

When you play a Java server with Geyser installed, Bedrock players have a prefix before their username, the prefix is `.`, so make sure to include this prefix if you want to add them to the whitelist or give them operator rights, e.g., if your username is `Alex22_SV` and you want to give them operator, use the command `/op .Alex22_SV`. You can also remove their prefix in the Floodgate configuration (not recommended because this helps differentiate the Bedrock players from Java players).
