Showing an occupied Unit: tenant wants to be there; I don’t!

[Susan Payne]

Hi, I have a tenant who has given a 30-day notice.  We were not a great fit; it’s not horrible, but I’m glad she’s decided to leave.  She wants to be present when I show the Unit to prospective new tenants, which I think is incredibly awkward, and just wrong.  What would you say to encourage her to please make herself scarce during showings?  I don’t 100% understand her reasons for wanting to be there; when I have had repair people in (at her request) I of course assured her that COVID precautions were being taken and no-one would touch “her stuff”. Ideas to encourage her NOT to be present?  Thanks.
