Where is LearnMoreUrl of custom data connector used in PowerBI Desktop?

[Anonymous]

Hi, I see that there is a LearnMoreUrl field in UI publishing part code of building PowerBI custom data connector, but I did not see where it is used in PowerBI Desktop. Could anyone show that where it is used? Thanks!
