Help me identify this app in TV+'s Home Before Dark

[GuillaumeB]

Hello,

I am currently watching Home Before Dark on Apple TV+ and out of curiosity, I was wondering the real name of the publishing Mac app that is constantly shown in various episods.
It sort of looks old, as if Microsoft had been porting Publisher on mac ten years ago 😨
It looks like it is called "Editor", but I can't find it. Is it actually real ?
(Had to take a photo of my screen as Apple blocks screen capture whenever Apple TV is running)

Thank you

Weird. It looks like some old version of InDesign or something. Seems like a lot of work to mock up a fictional app UI, but I could see it being fake.
