How do you delete roles in Parse.com using Cloud Code - parse-platform

Question

How do you delete roles in Parse.com using Cloud Code? I checked: https://parse.com/docs/js/symbols/Parse.Role.html, and it doesn't document any destroy method.
I am creating a role for every group of members, and I'd like to get rid of the role when the group is destroyed. What is the correct way of doing so?

Answer 1

Have you seen:
role.getUsers().remove(user);

Answer 2

This one works for me:
const roles = await new Parse.Query(Parse.Role).find();
await Parse.Object.destroyAll(roles, {useMasterKey: true}};

Answer 3

I played around with this for hours before getting it to work by fluke (no thanks to deficient and incorrect documentation)...
This is architecturally incorrect but the only way I could hack it together was using async function with await + promise... I do not understand Parse's weird mechanics sometimes. It's a love & hate relationship!
// Get user to delete object
let userToDeleteObject = await new Parse.Query(Parse.User)
.equalTo('objectId', userToDelete)
.find({useMasterKey: true});
// Remove user from group role
let roleDeleteQuery = new Parse.Query(Parse.Role);
roleDeleteQuery.contains("name", groupName);
roleDeleteQuery.first({useMasterKey: true})
.then(function(roleObject) {
roleObject.relation("users").remove(userToDeleteObject);
roleObject.save(null, {useMasterKey: true});
});
