bug report => please fork one of these codesandbox examples with a repro of your issue and include a link to it below

Current behaviour:
The button with the class imageButton searchButton is missing an accessible name and does not provide a description of its functionality.

Expected behaviour:
The button should have an accessible name that provides a clear description of its purpose. For example, it could be displayed as "Search Button" if it initiates a search action.

Steps to reproduce:

1. Navigate here.
2. Hover the mouse over the imageButton searchButton.
   
3. Observe that no tooltip or description of the button’s functionality appears

Proposed Solution:
Add an aria-label attribute or use the title attribute to provide a meaningful name.

Other information:
This issue fails to meet WCAG 2.1 Success Criterion 4.1.2, which requires that interactive elements, like buttons, must have accessible names.
