If you are using an RTL version of WordPress, then theme automatically will load all necessary styles for RTL mode.
If you are not using RTL version of WordPress, via Appearance > Customize > General Styles > RTL you can enable RTL styles for your site.
Please note: Because some of the elements styles are Dynamically Created and all are Editable, it may you couldn’t see them correctly in RTL mode, But you have access on all elements on any pages you created or imported from demos. So you just need to Edit page then edit element and fix the problems.
Usually problems is related to margins, so after editing element find style kits and just edit margins.
