There is no way to answer your question without knowing what the circuit diagram looks like. I believe you are correct, the circuit is probably designed for low-voltage “plug-in power”. That would NOT be compatible with 48-volt phantom power as would be expected on XLR connections. So connecting directly from the JST connector to XLR is NOT recommended.
You could add a circuit inside the microphone to adapt it to 48-volt phantom power, or you could use an external adapter (such as the “PFA” from Naiant). The Naint PFA is probably more practical unless you are an experienced service technician.

I would go here: https://www.sounddogs.com/extendedsearch.asp and search on: supernatural
I heard several similar sounds. Note that the sound in your example was almost certainly created from layering several different sounds.

It looks like it might be a “JST” (Japan Solderless Terminal) connector, but impossible to say for certain just based on your photos (with no scale).
If it is a JST connector, 4-pin female cable-end JST connectors are available from a wide variety of places for < $5. They are commonly used for charging batteries for remote-control toys. For example: https://www.all-battery.com/jst-xhv24pinadaptersforany3cellpack.aspx

It may be difficult because of where you are. There have been dis-honest people who have made a bad reputation for buyers in Eastern Europe. Do you have any friends who know and trust you in the US?

I use only PCs which is why I suggested that someone with Mac experience would be of better help. I must say that my strong suspicion is that this is an operational (or configuration) problem, and not a hardware problem.
It would be good to know whether the “Monitor On-Off” switch position has any effect on the symptoms. And a comprehensive description of the setup and operation would be necessary for any significant assistance.

I have a UCA202 and I have not encountered any such behavior. It may be possible that you have a bad unit, but that could happen with any brand. I don’t share others’ low opinion of Behringer. We don’t all drive Lamborghinis or use Sound Devices or Nagra, etc.

Without a sample to listen to, we are really just guessing. You may need someone to help you who is familiar with Mac hardware and software.

“When I disconnect the audio inputs from the UCA202 the … noise remains. Disconnecting the UCA202 makes the noise go away.”
That would appear to implicate your UCA202, wouldn’t it?
-
The high-pitch noise appears WHERE? WHEN?
Where are you hearing this? In headphones? In speakers? In the same room with the open microphone?
When are you hearing this? While recording (or setting up for recording)? Only when playing back the recorded clip?Does disconnecting the audio inputs from the UCA202 make the noise disappear?
Does disconnecting the UCA202 from the computer make the noise go away?
