+### AutoLaunchProtocolsFromOrigins
+Define a list of external protocols that can be used from listed origins without prompting the user. The origin is the scheme plus the hostname.
+
+The syntax of this policy is exactly the same as the [Chrome AutoLaunchProtocolsFromOrigins policy](https://cloud.google.com/docs/chrome-enterprise/policies/?policy=AutoLaunchProtocolsFromOrigins) except that you can only use valid origins (not just hostnames). This also means that you cannot specify an asterisk for all origins.
+
+The schema is:
+```
+{
+ "items": {
+ "properties": {
+ "allowed_origins": {
+ "items": {
+ "type": "string"
+ },
+ "type": "array"
