Lottie to GIF animation in Figma

Hi everyone,
i’m experimenting with lottie and used the figma plugin to upload my lottie animation into my futur client website.

In order to get an animated preview in figma i choose to convert my lottie animation into a GIF and here come’s the problem.

My animation is supposed to have a transparent background and when i export the GIF, he is transparent but has poor quality.

Link to the lottie file : https://lottiefiles.com/share/ngwa838d
Gif export : https://www.figma.com/proto/ty3LQXpTD3YpJn5qUbawF5/Untitled?node-id=0%3A3&scaling=scale-down

Can someone help me figure this out ? I didn’t saw any post about transparent background lottie animation on the forum.

Thank you very much !
