Power BI Client triggers, by different operators

[Anonymous]

Hi,

I have Desktop Custom Connector (that connect to Web URL)

I understand it is triggered by Power BI Client, by different operators:

I recognized it is triggered 3 time when the establish phase heppaned

- on Establish connection -> Navigator page appearse (preview), and when I click on Load, or Transport Data -> Apply 

I recognized it is triggered when a client click on 'Refresh' the model / dataset (based on this connector) -  refresh on Desktop or on Service - trigger it the same

My question is -Can I / how can I "know" in the connector what was the trigger? what was the client operation that executed this connector?

Thanks
