Anyone get approved for two week quarantine from their employer ahead of due date?

Hi all! I work in person and hoping to join my husband who has already been approved to quarantine for two weeks prior to our birth/due date under FFCRA:

If you were approved, can you share how? What did your doctor write to get approved? She’s already recommended it, but my employer is asking for a letter from my medical provider since the quarantine, per FFCRA, is being recommend by my medical provider. TIA.
