I don’t think Electra currently supports pitch bend.
Pitch pend is sometimes used as a controller to give finer control over something.
In Logic Pro X I can’t seem to find a way of mapping anything other than CC7 messages to controls within logic. For the most part thats fine
But having only 127 values for something like a volume fader isn’t really granular enough.
Logic Pro X though will map volume to Pitch Bend messages as this is something that is used by the Mackie Control Protocol
At the moment I’m trying to use an Electra 1 in preference to a Behringer XTouch to control Logic
Maybe worth considering for a future update
