Shimano Di2 SW-M8150-IR, settings

[der_luda]

I have the following question and please,
Unfortunately I can't find any information about how to adjust the shift levers for this Shimano di2...
Shimano advertises the di2 shifters with adjustable levers, but unfortunately there is not a single explanation as to how?

Thanks

There are allen screws on the shifters to adjust them
