How to reduce the size of a GIF?

Hi
I have a problem with a usercase made with Figma. Some of my slides are animated with micro-interactions and the only solution I found is to take a screenvideo of the slide and export it as an animated GIF via Premiere Pro. However, the issue is that the GIF file is over 100 Mo.

I would like to know how I can reduce its size.
Thank you.
