Indicator Upower Configuration Question

This is a great app that I have working on one device (OP3T, stops the charging process and sends notification to disconnect) and not so much on another (XperiaX, sends notification but continues charging regardless of set limit)

This comment on the gitlab pagesuggests further action by the user in order to configure the charging limit feature:
"It's a feature which needs to be enable on the device itself.
Please create a bug request against the repository of your device and mentions this commit..."

Can somebody tell me, does this need to be done, and if so where can I find the repository of the device? I've looked on gitlab and git hub but can't find anything that matches the description so far.

Note: The Xperia X is on the fredldotme/devel version.

@ziggutas Maybe I'm just not understanding the quote "It's a feature which needs to be enable on the device itself.
Please create a bug request against the repository of your device and mentions this commit..."?

Does it simply mean make a regular bug report on git hub?
