2. Install coherence

Now open Window > Package Manager. Select My Registries in the Packages dropdown.

Highlight the coherence package, and click Install.

Alternative method: edit manifest.json manually

Refer to Unity's instructions on modifying your project manifest.

Edit <project-path>/Packages/manifest.json.

Add an entry for the coherence sdk on the dependencies object, and for the scoped registry in the scopedRegistries array:
