Answer 1

Find this text in the source code. If you find it, remember the html element in which it is located, and search by its id/class

Answer 2

It would be more correct to copy the language file from en to ru and translate it completely there, and then select Russian in the admin panel. Otherwise, when updating the module, your changes will be rolled back.
