How do I hide an Outlook JS Add-In for OWA, but not for other applications (desktop outlook, Office365)?

Is there an option in the manifest.xml to stop the Add-In from appearing in the OWA app ?
It appears that FormSettings is a mandatory field, and at least one Form is required.

There are some functional parity issues with OWA (e.g. UI-less action, TaskPane for EditItems) that push us to forego having it there.

Thanks!

Currently the feature : "showing add-in on specific platform" , you requested, is not a part of the product. We track Outlook add-in feature requests on our user-voice page. Please add your request there. Feature requests on user-voice are considered, when we go through our planning process.
