WPBakery Page Builder grid builder how to display time of event

Question

I'm currently building a WPBakery custom grid to display events (my events are handled with Event Manager), I saw I can add a custom field but I cannot find the correct Field key name.

Does someone knows which key name I am supposed to use?

Already tried event_start_time, _event_start_time, event_time, _event_time...

Answer 1

I'm using this key:

event_begin
