hello everyone

I have installed deeplink plugins ( and it didn’t work for me.

when i click <a href=“capmission_client//”></a> it not open my apps !

my deeplink plugins configuration :

    <plugin name="ionic-plugin-deeplinks" spec="1.0.19">
        <variable name="URL_SCHEME" value="capmission_client" />
        <variable name="DEEPLINK_SCHEME" value="https" />
        <variable name="DEEPLINK_HOST" value="" />
        <variable name="ANDROID_PATH_PREFIX" value="/" />

i have added it in my app.component.ts and in my app.module.ts in Providers:
