Help with animation (pulsating dot)

Hi!
I’m trying to recreate this animation in WeWeb:
animation-blue-dot

I also found this example online(animated blue dot pulse):

I’m not sure where to start.
Are there any tutorials or can someone give me some pointers?

Thanks!

Have you seen JP’s video here: https://www.youtube.com/watch?v=LFrWquOaEC4&t=178s

That should answer your question.

Thanks @andreas, I haven’t had a chance yet to watch his videos in depth but it seems like a good start indeed.
