HTML link to download Direct Purchase version

After buying the direct purchase version (for degoogled phone without Play Store), the link to download the app redirects to a Google Drive.

Would it be possible to host the APK file on a normal HTML page ?

Because a lot of people without Play Store use some sort on updating app like Obtainium to check and dowload for an update, but this is not compatible with Google Drive wich require a user action with Javascript.

Thanks !
