I went on their website, https://www.fedi.xyz/faq . I cannot find the link to their repository or the link to their apk package. Where did you download it from?

From their FAQ:
You download Fedi from the App Store (currently in test flight) or Google Play Store (beta access) and then scan a code provided to you by a particular Federation to join it.
They might not have "unofficial" release channels yet.
