Do I have to set up royalty addresses on OpenSea if I already did so through the Manifold interface?

Hi all! Wanted to check in regarding royalties and OpenSea.

As I understand, as long as the contract has been deployed and a mint has happened before 1/2/23 they will respect on contract royalties. What I’m not sure is if have to declare the royalties setting on both places.

If I specify royalties through the manifold interface, do I have to do it again at OpenSea? Worried that if I add the addresses on OpenSea on top of doing it on Manifold they will be taken out twice.

Thank you for your help!
