Docs multi-instance

In this use case, you have multiple sets of documentation (a.k.a. Docs Multi-instance), then you need to add a reference to sidebar-schema.js into the dedicated instance of @docusaurus/plugin-content-docs:

docusaurus.config.js

plugins: [
  [
    "@docusaurus/plugin-content-docs",
    /** @type {import('@graphql-markdown/types').ConfigOptions} */
    {
      id: "api",
      path: "api",
      routeBasePath: "api",
      sidebarPath: require.resolve("./api/sidebar-schema.js"),
      // ... other options
    },
  ],
],
