Setting the Category of an Email through an HTTPS PATCH request

Question

I want to send a PATCH request to set the "categories" collection of an email to a value say "XYZ". What's wrong with the following HTTP request in Microsoft Graph Explorer and how can it be corrected?

PATCH

https://graph.microsoft.com/v1.0/me/mailfolders/inbox/messages?$Id=&"correctidofemail"&$top=1

Request Body:

{"categories": ["XYZ"]}

Generally, the question is how to set the categories of emails in Outlook from an HTTP PATCH request as described above. Is it possible at all? Are there any examples?
