Why can't I move if Simulate Physics is enabled on the CapsuleComponent?

Enabled Simulate Physics on the CapsuleComponent of the Character in the FPS Blueprint template and now I can’t move. Is there a reason why this doesn’t work?

Is there another way to have physics applied to the character so they can for example slide down a ramp with low friction, or be pushed by a moving object?

that should be on the mesh. Because the mesh is typically confined within the capsule component, the capsule component using physics is restraining the character.
