How to set up app hosting with my codebase?

I’m attempting to host plasmic studio in my app so I can implement some custom components. I’ve confirmed that the host url is working in my app. But when I configure my project with the app host URL - nothing happens after I press Confirm. I’ve tried about 5 times to get this to work with no success. I tried both my local host and our deployment host and neither seems to work.

Any suggestions?

Hey Bill! I will send you a DM to request more info.
Thank you
