need an option of auto publish built flatpak to Github

[CNOCTAVE]

in linux shell, auto publish built flatpak to Github can run as this:

- run: gh release upload <GitHub tag> <built flatpak filename> --repo $GITHUB_REPOSITORY

See https://github.com/CNOCTAVE/octave_zstd/blob/master/.github/workflows/build-and-publish.yml , line 24.

Can't you combine both this action with another one to do the uploading ? i saw you opened a PR but then closed it and went with a fork...
