There's nothing wrong with how you started.
I noticed that you used
https as your scheme. In my testing, I will open a browser and get a 404 response when use HTTP or HTTPS scheme.
You can try the following steps:
Step1. Use a customized string as your scheme, such as 'myapp'.
Step2. Send a link to your web server page in your SMS message.
In the documentation, there has shown the other way: Deep-Link.
You can refer to this documentation from Configuring App-Linking in Android 6.0 and Add Android App Links for sample.
