Contoso has built a model-driven app to challenge their employees to innovate. The way the app works is Contoso management can submit challenges and then employees can submit ideas. For example, a challenge might be “Reduce factory emissions by 10%.” Employees can submit ideas for challenges and get funded once they get enough votes.
Contoso would like to announce new challenges in Microsoft Teams by posting some information about the challenge. Contoso’s users would like to be able to create this post from the model-driven Innovation Challenge app they use to manage the challenges.
You will be building an embedded canvas app that will let users start discussions without leaving the Innovation Challenge application.
The lab requires a PowerApps environment with a Common Data Service database created and the sample apps installed.
The following have been identified as requirements you must implement to complete the project.
R0 – User must be able to start new Teams discussion from the existing Innovation Challenge application.
R1 – User must be able to select the Team in which they would like to start the discussion.
R2 – User must be able to select the Channel in which they would like to start the discussion.
R3 – The Challenge name must be included in the chat message.
R4 – User should be able to edit the message before posting it.
R5 – The embedded canvas should not be visible if a discussion was already started.
