That's great! It's kind of troublesome on a local instance since you would need to configure an SSL cert or possibly issue a self-signed certificate. This post list several workarounds.
Another possibility would be to launch the Motif application in a local environment. You can do that by cloning the repo and running the following code:
npm install --legacy-peer-deps
npm run motif:build
npm run demo:build
npm run demo:serve
I tested it to work with the IP address of a local Neo4j docker image which I hosted on GCP.
Glad that you got it working on Aura though and can skip through this hassle
