I have an experience created and I do not see any "Use Experience" checkbox in the script editor.

You need to either be the owner of the experience or be authorized as a group member with the Experience Administrator or Experience Contributor box checked in the Abilities assigned to your role.  If not, that checkbox in the editor doesn't appear.

Also, you obviously need to be on a region where the Experience is enabled, or the script won't run properly.
