Welcome!

This plugin is not supported by elastic.
Note that some security features are available by default OOTB with the embedded basic license.

If you still have questions about this plugin, you need to ask their authors on their forum or GitHub repository.

Thanks,i have found the root of the problem.
Installed version 6.3.1 defaults to system variables，Streamlined 6.8.1 uses the default environment variables，Therefore, the corresponding plugin cannot be loaded.
