Is there any way to create a `CompletionProvider` that takes a `JSON/YAML` schema file as a base, provides the details and sends the result to the completion suggestion?

If possible, any example plugin that does the same?

You can provide a schema for the file at least via `com.jetbrains.jsonSchema.extension.JsonSchemaProviderFactory`

Do you have any documentation or an example plugin?  
I searched for the topic but couldn’t find it.

The extension point is called [`JavaScript.JsonSchema.ProviderFactory`](https://plugins.jetbrains.com/intellij-platform-explorer/extensions?extensions=JavaScript.JsonSchema.ProviderFactory).
