Return types MsGraphAdmin breaking multiple functions

[ITMobilityControl]

A lot of the functions have the return type MsGraphAdmin, which breaks a lot of the functions because they return for example an array.

Example:

    public function findAttachments(string $id): MsGraphAdmin
    {
        return MsGraphAdmin::get('users/'.$this->userId.'/messages/'.$id.'/attachments');
    }

The get function returns an array, but because the return type of the findAttachments is MsGraphAdmin you get an error.

In this case it should be:

    public function findAttachments(string $id): array
    {
        return MsGraphAdmin::get('users/'.$this->userId.'/messages/'.$id.'/attachments');
    }

Are there any tests which can be ran? They should catch these problems before they get pushed.
