Hello again 🙂
There's nothing particularly complicated in the export settings. The higher the quality, the better the result. My advice is to have a look at the user guide's dedicated section and play with the settings. Be aware that depending on your settings, the file size can significantly increase.
You might also consider using the APNG format. As stated in the doc:
APNG is a lossless animated image format that supports transparency, so no loss of quality will occur.
However, keep in mind that APNG is not as widely supported as GIF.
