How to open Android app from a link without asking user to select between browser or app the first time

Issue

I have managed to get App Linking working for Android where it opens the app when opening the specified url.

I am opening the url https://fir-trial-66e3f.web.app/stripesub

However it asks me whether I want to use the app or google chrome to open the link, with the options "JUST ONCE" or "ALWAYS".

I want it to automatically open in the app the first time and to not ask the user.

I have tried following the instructions here (https://stackoverflow.com/a/34360396/10222449) by adding android:autoVerify="true" and I have verified my website. I did not need to upload the json file as it verified it automatically as I use the same google account as the firebase project owner.
However it still asks the same question.

I am using an Ionic app with Capacitor, however I don't think that is related to the issue.

AndroidManifest.xml

            <intent-filter android:autoVerify="true">
                <action android:name="android.intent.action.VIEW" />

                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.BROWSABLE" />

                <data
                    android:scheme="https"
                    android:host="fir-trial-66e3f.web.app"
                    android:pathPrefix="/stripesub" />
            </intent-filter>

Solution

Even though it auto verified me at search.google.com I still needed to generate the json file from within Android studio and copy to: myurl/.well-known/assetlinks.json.

To do this go to Android Studio -> Tools -> App Links Asssistant -> Step 3 Associate Website

I also needed to copy and paste it into notepad due to end of line issue (I think) and I put a carriage return at the end of the json or it wasn't working.
