How do I rotate/flip a selection in a tilemap?

If I try to select a part of the tilemap to copy and then try flipping it, it disappears. How do I make it not do that?

When copying and pasting tiles, use the built-in tilemap tools to ensure you’re copying the tiles correctly. Select the tiles using the "Rectangle Selection" tool in the Tilemap editor, then copy and paste them. Flipping tiles should work properly with these tools.

Sorry for the late response.

How do I copy paste them? Using control C and V after highlighting it doesnt do anything and trying to flip the brush with the selected area as the brush makes it dissapear.
