Lumen print question

Since I can't put 3 hours together to use my darkroom, I figured I might try some lumen prints (I have some old fogged paper). Do I really just need to rinse them after exposure or do I need to fix them? The paper is RC.
And, yes, it's not going to be sunny for awhile now that I want to do these.

I usually do a quick rinse because the plant won't lift off easily then I tone and fix them.
