Slack
Mention Floo with a brief; it answers in the thread with the finished frame.
On the Integrations page, choose Install in Slack and add the app to your workspace.
Ask for a design
Mention the app with a brief in any channel it is in:
@Floo a gift card page in the Kettle style, mobile first
Floo answers in the thread that it is on it, adds an Open design link once the run starts, and posts a picture of the finished frame when it is done. Mention it again in the same thread to revise the same canvas. An empty mention gets a hint instead.
Anyone in the workspace can mention the app; every run uses the installer's model key and lands as a private canvas in the installer's personal space.
Disconnect
Disconnect on the Integrations page stops mentions and pending Slack work. Existing canvases stay. To remove the app from Slack too, uninstall it in Slack's workspace settings.
