Has anyone successfully used TWO DJI Osmo Pocket 3 cameras as webcams on a Mac?

I’m trying to build a multicam streaming setup with two DJI Osmo Pocket 3 cameras on an M2 Mac mini running OBS.

Here’s what I’ve tested so far:

\- One Pocket 3 connected directly to the Mac = works perfectly.
\- Two Pocket 3s connected directly to separate
\- Thunderbolt/USB-C ports = also works perfectly (no lag or quality issues).

My problem is that one of those Thunderbolt ports is normally occupied by my Universal Audio Apollo Twin interface.

I tried using a GoStream as a workaround, but it introduces noticeable latency and lower image quality.

I also tried my current USB-C hub, but it’s not stable enough for this workload.

My goal is to run:

\- 2× DJI Osmo Pocket 3 cameras (webcam mode)
\- Apollo Twin
\- OBS
\- Dual monitors

Has anyone actually achieved this reliably?

If so:

\- What dock or Thunderbolt dock are you using?
\- Is your Apollo connected directly or through the dock?
\-Are both Pocket 3 cameras connected to the dock, or is one connected directly to the Mac?

I’d really appreciate hearing from anyone who’s running a similar setup before I spend more money on another dock
