Removal of Green Screen capability in Apple Mac version of Photo Booth

G'day all,

Years ago, I recorded a video using a "Green Screen" function within the photo booth app for OSX. Today, I had a client request something similar and straight away I went to show them the photo booth app but have found that either the function has been completely removed, buried away somewhere else or I am going blind...

Has anyone else found this or can confirm if Green Screen is still in the Photo Booth app for Mac OS Catalina 10.15.3?
