How do I Make a mining mechanic?

I want to make a mechanic like in minecraft where i can hold down the mouse and start to mine the block and wait a specified amount of time for each tile in the tilemap.

I am using a tilemap by the way

I dont know this is good for mechanic looks like minecraft, but you can try this

I use tile '46' for double clicking, so after click tile '46' i change it '44'.

Or if you clicking on tilemap != 46, you will erase it

Maybe you can customize it from that.
