How to create a mirror effect with TextMesh Pro text?

I have created a text and rotated in certain degrees in z axis.I created a copy and I want to keep it opposite side(consider car doors).I want to keep the same pose but the text appeared in mirror look.In order to keep the text appear normal I need to give a mirror effect so that it would appear normal.

 

I would have the same question in order to be able to mirror icons (such as arrows) from rich text tags.
