[shelly] energy item missing from channel for EM device

I have a Shelly EM and I’m wanting to capture the regular energy usage, I am using the trigger now to capture the updates to the Total Consumption calculating before-after however I notice there is a “energy” field output every min from MQTT but it doesn’t seem to have a matching channel item.
is it missing ?
or what is the best way to add it do the shelly addon or do I need to create this manually myself?
