Important gapi.auth2 notice: gapi.auth2 has been deprecated and replaced with Google Identity Services.

Summary
Safari, as well as all browsers on ios, default to blocking all popups. Unfortunately, this includes the auth popup that first is required for the drive picker to authenticate and then select a google drive file. Are there workarounds available to ensure browsers do not block this auth popup? On safari specifically, the first click attempt to launch the auth login modal is blocked, but subsequent clicks are not.

Browser(s)/Version(s)
Safari 15.6.1

Expected Behavior
The authentication popup should display when requestAccessToken is called (using tokenClient generated from google.accounts.oauth2.initTokenClient).

Actual Behavior
On calling requestAccesToken, safari blocks the auth popup from launching on the first attempt:

On subsequent attempts, the popup is not blocked and the authentication popup launches
