How do I make a physics object interact with my tilemap

Hi, Im having trouble with using physics objects, i want to make a crate that falls out of the sky onto the ground that can give players items, but im not sure how to get the crate (Which is a physics object) to actualy hit the ground (Which is a tilemap solid). Anyone have any tips on how i can fix this. Thnx

1-You can put an invisible physics object on top of a tile map and the box will hit it.

2-You can create a fall using bullet behavior.

Thanks for your help!
