Incorrect subscribe setting for workflow also affect other notifications

[tWatanabe0808]

Describe the bug
When configured subscribe setting without workflow details like as below:

/github subscribe twatanabe0808/our-first-react-app reviews,comments,branches,discussions,workflows,commits:*

Slack App responded as below:

It says workflows:{event:"pull_request" branch:your-default-branch} but this setting is notworking well not only for workflows.
In my environment, integration for issue and PR was not working well.

After I configured proper subscribe setting like below:

workflows:{event:"pull_request","push" branch:"main","develop"}

It works well. So it might be a bug.

Does anyone have same issue or any opinion?
