I'm trying to add a javascript library that requires a popup window for the user to log in, and when I call the library I can see the following error:

Possible Unhandled Promise Rejection (id: 3):

It seems that the line generating the error is this one

  const win = await window.open(url, "WaxPopup", "height=800,width=600");

It does not look like is a permission problem because the error point to a problem calling window.open, not sure if window would be a valid variable in React Native.

Any Ideas are welcome
