Is there any way to use the M121 4-Channel Relay module in UIFlow?

Is it going to use the same UIFlow Unit as the U097 4-Relay unit (that connects via Port A i2c)?

The U097 has some added features (the LEDs, NO and NC) that the M121 does not.

And if the M121 needs something different, how do I get that integrated with a UIFlow app?

I am brand new to using the m5stack and have no clue what works/doesn't work. So if there's a good newbie guide for integrating non-m5stack modules, please point me to it!

I'd like to control a seeed mosfet module from an m5go. This one:

Is it possible? I've got the module, a PaHub and the module cables. But I've no idea how to tell UI flow to add these units. I don't see a way to add other kinds of modules.
