Here is how you can enable coordinates in a Bedrock Server:
You can either go to the CONSOLE section of the control panel and type:
gamerule showcoordinates true
Or if you have Ops, you can type the command in-game
/gamerule showcoordinates true
What about your Java Editions?:
In Java Edition, pressing F3(or Fn+F3 on Macs and some laptops or Alt+Fn+F3 on newer Macs) brings up a debug screen which also gives the player's current coordinates.
