Help with Tubeless tires.

I just had a new set of Continental GPs put on my bike yesterday. This morning I went to put air in, and they were very low (60ish psi).
I hooked up my floor pump, and after reaching 85psi, I stopped pumping, and watched the needle slowly drop. I can hear air escaping, but no sealant is leaking out that I can find.

My question is this…do tubeless tires need to be ridden to get the sealant spread evenly everywhere?

I previously had the stock tubeless Bontragers that came on the bike. They never leaked. I had to replace them after getting a big cut on my rear tire.

Bike is a Trek Madone, SL7 Gen 8. Thanks!
