Hi @noeko0326,
Could you please tell me that how you link the department to the channel in the Teams?
Do you have each Channel to represent each Department?
Actually, there is an operation related to Teams connector named MicrosoftTeams.PostMessageToChannel, which send Teams message to a channel.
For me, to send message to each department once a visitor clicks the finish button, I will list all the Teams' name in a Gallery, then add another Gallery to list the channels in a Team, I select a team and then select a special channel to send the notification message to.
1). List all the teams in the Gallery by setting the Items property as:
MicrosoftTeams.GetAllTeams().value
2). List all the channels from the selected Team from the first gallery by setting the Items property as:
MicrosoftTeams.GetChannelsForGroup(Gallery1.Selected.id).value
3). Set the finish button OnSelect property as below:
MicrosoftTeams.PostMessageToChannel(Gallery1.Selected.id,Gallery2.Selected.id,{body:{content:TextInput_RequestInfo.Text,contentType:0}});Reset(TextInput_RequestInfo)
