Is there a way to start conversation when teams tab is created using graph api - microsoft-graph-api

Question

I am creating a teams app where there is an option to create a new tab for collaboration for individual/group by providing details like tab display title, url etc
After the tab is created, I would want to send some supporting message to describe about the tab.
Right now there is button to start conversation. And when you click on button some prefilled text loads along with tab title.
Is there a way I can achieve this using graph api, so instead of clicking on start conversation button and getting the pre-filled message, I should be able to pass the supporting message via the graph api ?
Or Can we customize the message shown once you click the start conversation?

Answer 1

once you create a Tab in Team's channel via graph api you should get 201 as success with ID of new tab.
HTTP/1.1 201 Created

"contentUrl": "https://www.contoso.com/Orders/2DCA2E6C7A10415CAF6B8AB6661B3154/tabView",

"removeUrl": "https://www.contoso.com/Orders/2DCA2E6C7A10415CAF6B8AB6661B3154/uninstallTab"
},
"sortOrderIndex": "20",
"webUrl": "https://teams.microsoft.com/l/channel/19%3ac2e36757ee744c569e70b385e6dd79b6%40thread.skype/tab%3a%3afd736d46-51ed-4c0b-9b23-e67ca354bb24?label=my%20%contoso%to%tab"
}
Then you can create conversation like below
