IsRepeat get input event struct ?

Trying to simulate a double click. I see there is a IsRepeat node which needs an input event structure but where can I get this from ?

If i had to do this, i would use branch, bool and delay node…
Input - branch(clicked 2x bool?) - false → set true, delay 0,3s, set false - true → fire doubleclick event

I’ve done it that way before. I’m really interested how to get some system structs working.

I see there is a “Get Input Event from Pointer Event”, but still no idea where this event can come from. I looked for an override but no luck there either.
