Baby shower panic

So this is the baby shower invite I sent in the snail mail to all my guests:

It clearly says virtually on the invite, with clear instructions on how to rsvp for access to the event. I sent these out a week ago and have only received 3 rsvp emails. I have also received gifts in the mail already but obviously won’t open them until the shower. I’m worried I should have put more information on the invite so people truly understand this is a virtual shower, and they need to follow instructions🥺

Does this seem approximately worded? I mean it’s too late now, but I’m wondering if I should reach out to those I invited. 🤷🏻‍♀️
