[BUG] Screensharing iOS native button doesn't go away

[tadaspetra]

Describe the bug The iOS native screen sharing button stays on the screen even when navigating to other pages

To Reproduce

1. Start a screen share, or just enable the iOS button
2. End the video call and go back to a different screen

Expected behavior The button is removed with the video call

Screenshots

Smartphone (please complete the following information):

• Device: iPhone 14 Pro
• OS: iOS 16.4
• Browser [e.g. stock browser, safari]
• Version 1.3.2

Additional context The ideal solution would be to only have one button in general, so that the screen recording is started from the AgoraButtons, and ended through the AgoraButtons, and of course doesn't show up when navigating back to previous screens
