Connection allows you to authenticate Integromat with Stencil
Most modules provided by Stencil in Integromat requires authentication to properly work.
Integromat uses Connection object to do this. When you use any module that requires authentication, you need to either add new connection or use existing connection.
The image below shows an example of
