The ChromeSafariBrowser's browser.close() method is not working as expected.

I'm encountering an issue with the ChromeSafariBrowser plugin where the browser.close() method is failing to close the browser window.

I'm utilizing 'ChromeSafariBrowser' from the 'flutter_inappview 6.0.0' package. After initiating a new browser window using browser.open() and subsequently attempting to close it after a timed interval via browser.close(), the browser window persists, obstructing the normal progression of my application.
