Transfer Fortnite account to another PSN?

I don't play Fortnite but my brother. And on my PlayStation. Since this annoys me every time I want to bring my brother a different Ps4, where he can play on a different account. However, he plays Fortnite on my account where I have all other games from me. I wanted to ask how I can transfer this Fortnite account from one account to another, so that nothing is lost and he can play with the same Fortnite account on the other Ps4, but with a different Psn account.

You need to sign up for Epic Games Online

Disconnect the link to the PSN account and create another account
