Metamask Mobile window.open() redirect

We want to redirect users to a custom URL within metamask mobile browser.

Using window.open(url) does not appear to be working in the metamask mobile browser.

We also tried redirecting to the users device browser using window.open(url, “_system”) but that did not work either.

How can we allow users to open a redirect link from within the metamask mobile browser?

Thanks in advance for any suggestions/guidance.
