[plugin-window] Tag action not found

Error message

[plugin-window] Tag action not found: ${actionName}

What it means

Dispatch guard in invokePluginMethod for runTemplateTagAction: a template tag matching pluginName and tagName was found, but it declares no action with the requested actionName. The missing action name is interpolated; check the plugin's templateTag.actions definition.

Solutions

1. Check the tag's declared actions and use the correct action name
2. Update the plugin tag to register the expected action
