Button syntax in EspoCRM 9.1.4

[rouhu]

I have added a button to detail view in file /custom/Espo/Custom/Resources/metadata/clientDefs/Requisitions.json
Its working fine in v8.3.4 but in v9.1.4 the button does nothing. It suppose to popup a window to create a related record (just like pressing the plus-sign in subpanel).

    "menu": {
        "detail": {
            "buttons": [
                "__APPEND__",
                {
                    "html": "CREATE APPROVAL",
                    "name": "approval",
                    "action": "createRelated",
                    "style": "success",
                    "acl": "create",
                    "aclScope": "Approvals",
                    "data": {
                        "panel": "approvals",
                        "link": "approvals"
                    },
                    "hidden": false
                }
            ]
        }
    } 

I wonder if this should work or if the syntax has changed ?
