Outlook插件InsightMessage功能无法正常实现的技术求助

我的Outlook插件使用ErrorMessage功能完全正常，但尝试实现InsightMessage及其关联动作时始终没有效果。目前能找到的有效资料只有微软官方文档和Stack Overflow上的相关问题。

我想要实现类似Viva的效果——显示包含操作链接的消息，但插件运行后没有任何反馈，打印result值仅显示存在错误，但无详细错误信息。

相关代码片段 #

Office.context.mailbox.item.notificationMessages.replaceAsync("messageKey", {
    type: Office.MailboxEnums.ItemNotificationMessageType.InsightMessage,
    message: email.Notification.Message,
    icon: 'TeamsAssistLogo64x64',
    actions: [{
        actionText: 'Open insight',
        actionType: Office.MailboxEnums.ActionType.ShowTaskPane,
        commandId: 'msgReadOpenPaneButton',
        contextData: JSON.stringify({ a: 'aValue', b: 'bValue' })
    }]
})

疑问 #

• 插件如何识别另一个任务窗格插件？
• TeamsAssistLogo64x64.png已在任务窗格清单中定义，是否配置正确？
• 不确定msgReadOpenPaneButton是否正确，任务窗格清单里包含<Control xsi:type="Button" id="msgReadOpenPaneButton">
