2. Click the **Edit Catalog** option on the top right side of the page.
3. You can update the **host** and **access token** if desired.
4. Select/deselect **schemas** as required.
5. To enable automatic catalog updates, toggle on the auto-refresh option and set the desired time interval for catalog updates.
