Issue with Send Email Alert in ERPNext Workflow

I want to configure an email alert in the Workflow doctype.
I have set up the email domain and email account, and I did not tick the Only If Creator or Is Optional State checkboxes.

However, the email is still not sent automatically when the document moves to the next workflow state.

When I set it up using a Notification and manually send the email from the Email Queue, it works well.

Could you please advise how I can configure automatic email sending in the Workflow?
