How Do I Politely Follow Up with HR After Being Shortlisted for a Job?

I attended an interview on [insert date] and received an email from the HR department stating that I have been shortlisted for the position. I was informed to expect a call shortly. However, it has been about three weeks now, and I am seeking guidance on how to compose a follow-up email. I would like to inquire about when I can expect to join or any relevant information concerning the position.

Thank you for your assistance.
