- [ ] The Teller page currently lacks a "Go Back" button, preventing users from easily navigating to the previous screen. This impacts the overall user experience and flow of the app.

**Steps to Reproduce:**
- Log into the app as a teller.
- Navigate to the Teller page.
- Observe there is no "Go Back" or navigation option to return to the previous screen.

**Expected Behavior:**
Users should see a clearly labeled "Go Back" button or navigation option to return to the previous page or dashboard.

**Actual Behavior:**
There is no visible option for the user to navigate back, which can cause confusion or force users to restart the flow.
