I am a beginner with Google App maker. I want a custom calendar event similar to 'outOfOffice'/AppointmentSlots'. I used the tasks add on there is a new event type called 'Task' appearing when I try to create an event. 
Also, There are new interactions with a task event type
I would like to create a new event type similar to tasks and new interactions when the event is clicked on. I am hoping that AppMaker would help me achive this. I did not find any api support in Google calendar for creating a new event type. Please advise
