 Each global header entry requires the following attributes:
 
 - `mountPoint`: Defines where the header will be added. Use `application/header` to specify it as a global header.
 - `importName`: Specifies the component exported by the global header plugin (e.g., `GlobalHeader`).
-- `config.layout.position`: Determines the header's position. Supported values are:
+- `config.position`: Determines the header's position. Supported values are:
   - `above-main-content`: Positions the header above the main content area.
   - `above-sidebar`: Positions the header above the sidebar.
