grip shift

I have a pair of Ergon GP3s with a factory shortened right side for twist shift internally geared hubs (Enviolo Nuvinci, Rolhoff, etc.) but my warranty replacement bike from Evelo uses Enviolo Automatiq which doesn't need the space so I'm hopping to get a standard version right side grip, either...

I’ve ordered a 12 speed Gx Gripshift for my Cube as I’m getting a lot of arthritic thumb pain using the trigger shifts but I just realised that none of SRAM’s grip shifts mention that they are suitable for eBikes. All the trigger shifters seem to have ebike specific variants! Is there any reason...
