You don't have the permission to perform custom action CreateNegotiationResponse. (PON-2085785)

Summary:

I'm migrating to the new Redwood experience and I'm getting the following error: You don't have the permission to perform custom action CreateNegotiationResponse. (PON-2085785).

I already have the privilege assigned according to the version 25D documentation; however, the error persists. I've also submitted a support request, but they only told me to remove the privileges from the vendors, which I've already done. I'm working with the standard Category Manager role.
