UI/UX Secondary menu with a single entry

I have a question of ux/ui design : is it a good practice to use a dropdown menu in a vertical 3 dots button with only one option in there ? Is there an alternative?

Example :

A page allowing to edit the content of an email, we want to add a secondary action allowing to reset the content of the email (to its default content). In a card list, for each card add an option to export it in xls.
