+
+You can use the [EdgeSidebarAppUrlHostBlockList](/deployedge/microsoft-edge-policies#edgesidebarappurlhostblocklist), [ExtensionInstallBlocklist](/deployedge/microsoft-edge-policies#extensioninstallblocklist) and [EdgeSidebarAppUrlHostAllowlist](/deployedge/microsoft-edge-policies#edgesidebarappurlhostallowlist) policies to allow specific sidebar apps, (except the Search app) while blocking the rest of the sidebar apps. To allow the Search app, see [Allow the Search app](#allow-the-search-app).
+
+Use the following steps as a guide to exempt a specific sidebar app from the blocklist.
+
+1. Follow the **second option** in [Block all sidebar apps](#block-all-sidebar-apps) to block all sidebar apps.  
+2. In the group policy management editor, go to **Administrative Templates** > **Microsoft Edge** > **Extensions** and then select "Allow specific apps to be opened in Microsoft Edge sidebar".
+3. Select **Enabled**.
+4. Click **Show**.
+5. Enter the URLs or URL patterns of the sidebar app that you want to allow. For more information about valid URL patterns, see [Filter format for URL list-based policies](/deployedge/edge-learnmore-ent-policy-url-patterns).
+6. Click **OK** when you're finished entering URLs. For example, *[\*.]youtube.com* in the next screenshot.

+
+The Search app doesn't have a URL. You can only use the [ExtensionInstallAllowlist](/deployedge/microsoft-edge-policies#extensioninstallallowlist) policy to allow the Search app while blocking the rest of the sidebar apps with the [EdgeSidebarAppUrlHostBlockList](/deployedge/microsoft-edge-policies#edgesidebarappurlhostblocklist), and [ExtensionInstallBlocklist](/deployedge/microsoft-edge-policies#extensioninstallblocklist) policies.

+   - The Search app Extension ID (`extension_id` parameter), shown in the next screenshot is "jbleckejnaboogigodiafflhkajdmpcl".
+   - You can also find Extension ID for Search app by going to *edge://sidebar-internals*.
+   - The Sidebar internals JSON file includes a manifest for all sidebar apps, including an `extension_id` parameter for each app. You can use these values to configure the policy.
