Press F3 on your keyboard because you can also see X / Y / Z what your current coordinates are, then you can write the coordinates in Minecraft in a book so that you always have them

Two possibilities:

You write the coordinates with blocks on the floor
You name a banner after the coordinates, place it there, and right-click it with the map
