 This module can be enabled/disabled for specific rooms. Only one of the following settings must be set.
 ```
--- muc_http_auth_enabled_for = {"teaparty"}
--- muc_http_auth_disabled_for = {"teaparty"}
+-- muc_http_auth_enabled_for = {["all"] = {"teaparty"}}
+-- muc_http_auth_disabled_for = {["all"] = {"teaparty"}}
 ```
 If none is set, all rooms in the MUC component will have this module enabled.
