I’m trying to figure that out. There is a 5v, grd, and tx3 and rx 3 that may be usable for a buzzer. It says for “other module”.

That’s a good question! The one of the possible ways is to use M5 or M6 pads and remap the resoources. But the problem is you cannot solder the active buzzer directly to the MCU outputs because buzzer draws more current than MCU pin output can sink. Usually buzzer output pads (BZ+ BZ-) have additional circuit – power transistors to control the buzzer. You probably can use the so called Buzzer – lost quad finder with built in battery. It should have it own circuitly to drive the buzzer.
