Zaraz timer trigger or load by scrolling event

is it possible to use a timer trigger or to load on scrolling event by the visitor?

My intention is to optimize speed.

Yes

The problem I deal with is what I want to rebuild this trigger in Zaraz → "Click -Just Link) click URL Contains. I did not find a solution yet.

what’s the issue?
use the Zaraz Debugger to understand why your triggers are firing or not firing.
