Not sure where you read it is bridge supported, the only place I’ve made it publicly is on the (community) app list here on the forum, and there it is nicely in the list of “test channel” apps.
Also the reason why it isn’t in the list when you type the manufacturer’s name, it is still in test fase, and thus not showing up on the stable apps in the mobile app.
Making a test app available to everyone for installing can cause many confusions and give issues, as there can still be issues.
Making it very entry level, as an app with issues isn’t very user friendly.
An update is still in the works for the one in the test channel (the current test version was declined by Athom for the stable channel), which will also include an updated inclusion description, as that is one of the points.
