‘Unlock With Patreon’ Button to open to a new tab

Hi, I have converted my website into an android app. However, inside an android app it is not allowed to login third party app or OAuth. So patrons who uses my app and want to unlock gated content unable to do so inside my app because it needs them to login into Patreon and do OAuth.

The only possible way is for them to login and do OAuth in a web browser, after that they can return to the app and the content will already be unlocked.

So my concern here, can I make the ‘unlock with patreon’ button and the ‘refresh if you are existing user’ link in the gated content to be opened in a new tab so that it will bring the user to a browser instead of opening the window in my app?
