Description:

searchMessages function is invoked repeatedly after the user stops typing in the search Messages input box, causing multiple API calls, which may lead to increased server load and decreased performance.

Steps to reproduce:

1. Click on the three dots at the header section -> Click on Search Messages
2. Open the browser developer console -> search for some message
3. In the Networks tab, you can see the Multiple API calls being made

Expected behavior:

After the user stops typing, searchMessages should be called only once after the specified debounce delay (e.g., 500ms).

Actual behavior:

After typing stops, searchMessages continues to be called repeatedly, resulting in multiple unnecessary API requests.
