Tried to add keyboard shortcuts to trigger switch access commands. Maybe missing a permission.

chrome/browser/resources/chromeos/switch_access/manifest.json.jinja2

 {
 {% if key is defined %}
   "key": "{{key}}",
 {% endif %}
   "manifest_version": 2,
   "name": "TODO: Translated Switch access name",
   "version": "{{set_version}}",
   "description": "TODO: Translated Switch access description",
 {% if is_guest_manifest == '1' %}
   "incognito": "split",
 {% endif %}
   "background": {
     "scripts": [
       "switch_access.js"
     ]
   },
   "permissions": [
-    "accessibilityPrivate"
+    "accessibilityPrivate",
+    "commands.accessibility"
   ],
   "automation": {
     "desktop": true
+  },
+  "commands": {
+    "previousItem": {
+      "description": "Move to the previous item",
+      "suggested_key": {
+        "default": "Alt+B",
+        "chromeos": "Ctrl+Shift+1"
+      }
+    },
+    "nextItem": {

+      "suggested_key": {
+        "default": "Alt+N",

+      }
+    },
+    "selectItem": {

   }
 }
