Can not open another app use scheme url from Metamask Ios browser

**Describe the bug**
I can not open another app (I use Telegram app for example) by using Scheme Url from Metamask iOS browser
I use this code to open Telegram app:
html code: Open telegram
or javascript code: location.href = "tg://";
This code worked on Safari iOS , Chrome iOS , event Metamask Browser on Android. But not worked on Metamask Browser on iOS

**To Reproduce**
1. Open Metamask app on iOS device (iPhone), switch to Browser
2. Open a Dapp in a new tab
3. In Dapp, open another app by scheme url. Ex: Open Telegram by html tag: Open telegram
4. Nothing happened

**Expected behavior**
Open app Telegram when call redirect to Telegram scheme url in step 3.

**Smartphone (please complete the following information):**
- Device: iPhone 6s
- OS: iOS 15.2
- App Version 3.4.1 (785)

- Is this visible to all users?
- Is this tech debt?

No implementation file, test, or entry point is named. First reproduce the scheme-URL link in the MetaMask iOS browser on the reported iPhone/iOS setup, then trace the browser's external-app URL handling; done means a tg:// link opens Telegram as it does in Safari and Chrome.
