Add mailbox icons

Please add mailbox icons with mailbox door open and one with closed. I placed a tilt sensor on my mailbox so alexa will anounce when the mailbox door is opened and closed. I also placed a virtual contact sensor on my dashboard to show its status. Alas, i cannot find a mailbox icon to place on it. I also have a hubitat rule to notify me if it is open for 5 minutes. Thank you very much.
