If you've scheduled classes in Zoom and enabled the 'meeting room' feature, you can also customise it with your own logo.
i. Go to Zoom.US
ii. Click on My Account
iii. Choose 'Settings' > 'Meeting'
iv. Scroll right the way down to where it says 'Waiting Room' (or search for it) and make sure it's set to 'on'
v. Click on the pencil icon to 'Customize Title, Logo and description' and update with your own personal details
vi. When parents join, they'll then be greeted with something like this!
