How to add custom Colliders to Custom Mesh

Hey guys hope you are well

I’m trying to remove and add my own colliders to a hovercraft I downloaded on Unreal Marketplace. But since it’s not a static mesh, I can’t find the ‘Collider tab’ that’s usually in the top-bar of the screen.

Can anyone maybe help me to understand where the collider settings are for this mesh and how to remove and add my own colliders?

Here’s a screenshot:

Any help would be appreciated immensely!

Thank you for your time

Kind regards
