[SOLVED] How to retarget animations bought in Marketplace?

Hi,

I bought this animation pack Female Superheroine Animation Pack in Animations - UE Marketplace . I want to use them on a Metahuman. The animations are compatible with UE4 mannequins, and the pack has a female mannequin, so I think I have to retarget the animations. When I open a RTG asset, none of the animations from the pack appear in the list. How to retarget animations in a situation like this?

Just to clarify: I created a new Level Sequence, added UE4 Mannequin, and there´s just one animation available for it:
OneAnimation

But, I have 30 animations in the same project:

Why all that animations are not showing in the animation list inside Level Sequence?
