This feature is called "mouse echo". It exists in both JAWS and NVDA, but is not enabled by default. It's primarily used in these applications so that blind people can use the mouse as a last resort to understand the screen layout and activate inaccessible controls.
However, some people with low vision find it useful. People who are visually impaired generally use ZoomText or other screen magnification software; they rarely use screen readers, and if they do, they are more likely to use screen reading and screen magnification together, like with the product Fusion, which combines JAWS and ZoomText.
Whatever software is being used for testing, you shouldn't need to change the code to have mouse echo unless the user has specifically chosen to receive that information by changing options in their screen reading or screen magnification software. It also shouldn't be something you need to design and test for since it nearly always works.
Here is some information you might find useful about mouse echo in Fusion: https://www.zoomtext.com/futest/
