To rename an interaction in Unity, follow these steps:
In the Unity editor, select the interaction object that you want to rename. You can do this by clicking on the object in the Scene view or by selecting it in the Hierarchy window.
Double Click (or use hotkey F2) to enter the rename mode for the object.
Rename it to the desired name.
Press "Enter" or click outside of the Name field to save the new name.
Open the Interactions Menu by going to the top menu bar, LLS > Interactions Menu
Selected your renamed interaction and press "Upload interactions".
If you are not seeing the change on the website, try to refresh the page.
That's it! The object's name will now be updated in the Inspector, Hierarchy, and website.
