Hide image from map viariable

I have a map in the game as a UI.

It contains level tiles, each level is a separate image.

I would like to have the option to hide and show it depending on whether the player has unlocked the level.

I tried to do this with the MAP variable

where I have the level name and a boolean to indicate whether the level has been unlocked

But from the level name, I don’t know how to show the appropriate level tile on the map.

I would like the script to check for unlocked levels (using boolean in save game) when opening the map, and then hide/show the appropriate tile.
