Possible to read/write can bus in node-red with venus nodes?

I think that using vecan and node-red I should be able to read and write the canbus using one of the available USB can adapters.

Does anyone know of an example? Do I have to install another node-red node module in addition to the VenusOS one? Is signal-K a better approach?

If it matters, I am using VenusOS on a RaspberyPi to control a solar array. I need to help some older SMA inverters talk to a newer SOK Lithium battery stack.

TIA
