Coordinate grid for the world map

Unity Engine

Hi all.
I need to put a grid on the map, and the size of the cells needs to be set within the game. It is also necessary that when the map is enlarged, the numbers and letters indicating the cells move behind the screen.
What is the best way to implement this?

ok, maybe it will be useful to someone. I made the grid through 2 loops - for each axis. I spawned a prefab in which there was an empty square PNG with black lines along the edges.
I’ll add more when I solve the issue with numbers…
