InApp/InWeb schemes
Set up the message measurements
Schemes define where a message will occur within your app or web.
That is, they are the measurements and position that the inApp / inWeb notification will take on the screens of your users' devices.
To create a scheme you must specify the parameters:
Name : descriptive name that will help you identify this schema during the creation of an InApp / InWeb message.
Code: is the identifier that your app / web should use to load the InApp / InWeb message in each gap.
Width and height: dimensions (in pixels) of the space that will be reserved in your app / web to paint the messages.
