In the custom action settings page, we have the “Variables” button in the “What Actions to Execute” section (See screenshot below).
Clicking the “Variables” button opens a dialog that shows existing variable definitions along with “New Variable” button (See screenshot below).
Clicking on the “New Variable” button opens a dialog and prompt to enter the variable name and default value (see screenshot below).

•Literal/Custom values
