How do I delete a callback function from an app in App Designer?

I cannot delete a callback function from my app using the procedure

described by the MathWorks Support Team dated 27 March 2019:

"To delete these functions, navigate to the Code View in App Designer. Then, right click on the callback in the 'Code Browser' pane, under 'Callbacks'.

Right click on the callback, then select 'Delete'."

When I right click on the callback, nothing happens. I cannot get a "Delete" to select.

Does the callback text hightlight when you click it as shown below?

Within App Designer, you can right click the callback under the 'Callback tab' within the 'Code Browser', which is on the left side panel. See screenshot below.

After right clicking the callback you wish to delete, select Delete as shown below.
