According to Microsoft Documentation it is possible to initiate actions with messaging extensions see https://learn.microsoft.com/en-us/microsoftteams/platform/concepts/messaging-extensions/create-extensions
To do so, the command must specify the "type" parameter with value "action" (MS example below)
"composeExtensions": [
{
"botId": "......",
"canUpdateConfiguration": true,
"commands": [
{
"id": "reassignTodo",
"description": "Reassign a todo item",
"title": "Create To Do",
"type": "Action",
"fetchTask": true
}
]
]
But according to Microsoft Teams documentation "Reference: Manifest schema for Microsoft Teams" the "type" property doesn't exist ! see https://learn.microsoft.com/en-us/microsoftteams/platform/resources/schema/manifest-schema
BTW, import existing app in MS Teams fails !
Is it a bug or, someone know why it disappears ?
