How to find sprite at grid location?

Hey!
I’m working for the first time with Tilemaps and grids in unity and…well I’m stuck.

I’m currently trying to make a Fire Emblem type of game, but I’m struggling at finding which sprite is present at a X,Y Coordinate in the world. I basically need this to prevent the player from being able to select the cell and move there… I’ve looked at the grid / grid layout documentation but was unable to find anything helpful.

I want to check if the ground tile’s sprite is red checkered, of so, remove my movement indicators (hollow light blue squares).

Try using Tilemap.GetTile(Vector3Int position).
