Deep linking from Web to PWA (Standalone Version)

Question

I have a web app that it can be installed as standalone application in the homescreen thanks to PWA standard.

When a user forget his password, a email is sent to him with a link to reset the password.

Can I deep-link to the already-installed standalone version instead of the web application in chrome browser? I'd like to achieve this behaviour:

• User clicks in email link from gmail application.
• OS check if link matches with any url schema pre-registered in the system (This is the step that I don't really know if it's possible from web right now)
• If found, open the standalone version. Otherwise, open the browser.

There is an example of describing intent filters in json here. The relevant section of the manifest is intent_filters

{   "manifest_package": "org.chromium.webapk.test",   "scope_url": "https://pwa.rocks/",   "intent_filters": {     "scope_url_scheme": "https",     "scope_url_host": "pwa.rocks",     "scope_url_path": "/"   },   "start_url": "https://pwa.rocks/",   "display_mode": "standalone",   "orientation": "portrait",   "theme_color": "2147483648L",   "background_color": "2147483648L",   "icon_urls_and_icon_murmur2_hashes": "http://www.pwa.rocks/icon1.png 0 http://www.pwa.rocks/icon2.png 0",   "web_manifest_url": "https://pwa.rocks/pwa.webmanifest",   "version_code": "1",   "version_name": "1.0",   "bound_webapk": {     "runtime_host": "org.chromium.chrome",     "runtime_host_application_name": "Chromium"   } }
