B4R Question B4R for M5Stack?

I am new on B4R, just found it today.
Would like to program the M5Stack (ESP32) with B4R.

I did a lot projects with Bascom, C, Arduino, etc. and AVR MCUs.

So, my simple question is:
Is M5Stack supported by B4R?
Can it be used with same libraries as in Arduino?
I have to use the display, UART, RS485, CAN and Wifi of the M5Stack.

Sorry for this question, but this is not really clear for me.
Unfortunately I have less time for experiments and searching for solutions, if M5Stack is not supported completely.

Thanks for your help in advance!
