Can I set the event to be triggered after watching the reward video multiple times?

Smite

I want to set up a reward video that needs to be viewed multiple times before triggering some events.

For example, if there are interstitial image ads in the game,

I set up a reward mechanism to turn off all intrusive image ads if the player watches the rewarded video five times.

I have watched YouTube on how to set up reward videos

But I don’t know how to set the cumulative number of times I watch reward videos?

There is Ad Reward Value in Game Attributes

If it means that the rewarded video appears, it will become 1, and if the rewarded video does not appear, it will become 0.

How to create a counter to indicate how many times the ad has been created?

Hope to get your help
