Not seeing “Custom Application” option in Layout Template sidebar in Workfront

Hi all,

I’m working on integrating an Adobe App Builder app with Workfront. I’ve created and deployed the app successfully, made sure the IDs are unique.

However, when I go to Setup → Interface → Layout Templates, I don’t see the option to Add a Custom Application in the sidebar.

Has anyone encountered this before? Are there additional steps or tenant settings required to make Custom Applications appear in Layout Templates?

Thanks in advance for any guidance!
