Moving mesh within a character blueprint

I made a targeting arrow so when you click a button your camera follows the target and shows an arrow above its head.
I want to make the arrow slowly move up and down in a loop but i cant find where i can do this or how i can animate this.
Can someone say how i can do this or if its even possible?

are you just looking for the arrow to essentially bounce on the characters head like a target marker kind of thing? if so then you could easily implement this via a timeline.

How could i do this with a timeline? Because that was exactly what i wanted the arrow to do.

If the bounce effect is just a continuous visual effect, you could implement it in the material of the arrow. That way you keep your blueprint cleaner, and can use the effect on other objects as well. I’ve attached a screenshot of an example material.

Thanks for the help! it works great.
