Electricity effect Three.js with r3f

[reigj1]

Hi, I have a Line geometry and I want to add an electric effect to it, similar to this:

Going from the start of the line to the end in a continuos effect. I dont need the things around the line, maybe a little glowing ball moving from the start to the finish, a sort of pulsating effect.
