Export Interactive Prototype (small file size)

I would love to export a fairly robust prototype with several animations and screens, in a file size that is much smaller than the document file size. When I “Export Mac App” it’s exactly what I want, just a massive file size that is, realistically, unsharable.

Is there any way to take the interactive prototype and compress it (reduce quality/file size)?

PS. for instance, I have a really simple prototype that the principle document file size is around 2.1MB…when I simply export for mac app that export file size is over 3MB…so just exporting bloats the file size.
