I am trying to add Additional invocation phrases on the Directory Information tab for a Smart Action on the Actions Console. After filling phrases in and pressing the Save button I receive a notification "Assistant app information saved successfully". But filled in phrases do not appear in the list under Additional invocation phrases. Also, I cannot see filled in phrases in the "Explore all actions" -> "What it can do" tab of Google Assistant for the Smart Action. I can find there only auto-generated phrases.
I've tried to fill in phrases with and without Action name or Device name, but nothing worked.
How can I add Additional invocation phrases to Smart Action? Auto-generated phrases partially don't match the functionality of my Action.
