How many clients can the R8000 — Nighthawk X6 AC3200 support with access points

I have a R8000 Nighthawk x6 AC3200 router, along with 6 access points from Unifi running throughout the house. There are usually about 60 people in the house, with a good amount of them on zoom calls for school at one time, and others streaming videos. I know that acting as the sole access point, the router can support around 50 clients, however, I don't use the router as an access point. I wanted to know how many clients the router can support with these access points and the traffic they bring in, as opposed to just acting as the sole access point.
