Hi @v-xida-msft,
Thank you for answering.
When news of SharePoint was published, I want to notify a channel of the Teams application.
I occur to only a method to carry out Flow every time.
Sharepoint trigger 'for a selected item' to start a flow.
↓
Action 'Get items'.
↓
Action 'Post message to Teams'
In addition, I want you to tell me the method if there is a method.
