Provide the ability to disable internal chat visual popups while keeping sound notifications

Affected users: Healthcare Professionals (Nurses and other clinical staff).

Task affected: Receiving internal chat messages in MYLE EMR while performing clinical tasks, such as writing and approving medical notes.

Impact: Frequent workflow interruption and visual distraction. The 30-second visual banner appears at the bottom of the screen, frequently blocking essential action buttons (like the "Approve" button for medical notes). This forces users to pause their work until the popup disappears or forces them to miss visual information.

Current state: There is no workaround to achieve the desired behavior. Currently, muting a conversation disables both the visual popup and the sound. Disabling the sound via the speaker icon keeps the visual popup. Users cannot choose to have only an audio alert without the intrusive visual banner.
