[AI Chat]: Listen Button State Does Not Reset After AI Answer Content Is Read Aloud

[Shoaibdev7]

Problem:

• When I click the Listen button, the text is read aloud. However, when the text is fully read and the voice stops, the button state does not change; it remains in the Pause state. When the text is finished, the button should revert to its initial state (Listen Button) but it does not.
