Important metadata missing in ttf file

[geekley]

Important metadata is missing in the ttf file (v0.6.0). The most important is license.
It's also important to add the corresponding Twemoji version (could be in description field or appended in version field).

For comparison, TwitterColorEmoji-SVGinOT.ttf (v13.1.0, Linux) has at least these:
Version: 13.1.0 20210621
Copyright: Copyright 2021 Brad Erickson CC-BY-4.0 Copyright 2021 Twitter, Inc. CC-BY-4.0
Description: A SVGinOT color emoji font using the Twitter Emoji for Everyone set: https://github.com/eosrei/twemoji-color-font
Manufacturer: 13rac1

So, I assume it should be similar, except having Mozilla as manufacturer and linking to this repo. And appropriate copyright for whatever version it's using.
