URL Scheme to open Safari from Facebook

Hello Apple team and fellow developers,

We are working on a website that requires users to allow microphone permission to interact with our web content.

However, when we open the website link from a Facebook post, it will always use Facebook-In-App-Browser.

And Facebook Browser doesn't have access to microphone permission.

So we're checking if there is a way to open the link in Safari browser from a Facebook post.

Here are some approaches that we tried:

1. Use Safari Scheme: https://codepen.io/felquis/pen/gPLrgv

2. Use FTP to open Safari successfully but we can't run the Javascript with this protocol to redirect users to our main website

Any help, tip or confirmation if this is possible or not are all appreaciate 😟.

Thank you so much in advance,

Nhan
