Editing manifest.webmanifest

How can I edit manifest.webmanifest file located at yourdomain.com/manifest.webmanifest ??

i want to remove that app(pwa) shortcuts when you long press on app(pwa) icon.

That is not possible at the moment, unless you overwrite this method in a custom plugin.

The plan is to make this configurable by site admins, but Iā€™m waiting for this bug to be fixed by the chromium team before working on that: 1091612 - chromium - An open-source project to help move the web forward. - Monorail.
