Where are my skins when I disconnect my ps4 acc from my epic acc?

I changed from ps4 to pc and wanted to separate the Ps4 acc. Where do my skins go? Will they stay on PS4 or can I keep them on my PC epic account?

Did you log in to your Ps4 with an Epic account?

If yes, just log on to the pc.

If not:

I'm not sure anymore because I have not been gambling for months, but I think there's a function on the pc how to sign in with the account and keep your skins.

So, if you sign up with your old account then you keep your skins.
