Multiple Mikrotiks not seeing Ubiquity AP

Hello,
I am attempting to wifi bridge a Mikrotik to an unknown model of Ubiquity AP.

I have tried with both a mAP lite and a hAP ac lite.

I tried both 6.49.6 and 7.5 on both units.

I am not seeing the Ubiquity SSID I need to connect to show up in Wireless Snooper on either 2.4 or 5.8 bands on the Mikrotiks.

The AP has two SSIDs on the same MAC address, I can see one of the two, but I do not have the key for the one I can see and it would not provide connectivity I needed, either.

I am able to connect to the desired SSID at the same location with laptops and my phone.

I’m a bit baffled.

Ideas?

Instead of bridging… Can you connect to the Ubnt as a client and make it the WAN. Then let the the Tik work like a router?
