particle (video) animation

Hi there,
I want to create a particle effect that pops up at the corner of the screen when the player picks up collectibles.
What would be the right way to do so? I came up with a flipbook texture or either a simple mp4 video.
the problem here is that the exported mp4 from blender couldn’t be opened at all in unreal engine and i found no tool to create a flipbook texture. Is it even the right way to use one of those two techniques?

Heres an example to roughly visualize what i want:
