I'm not the person you're replying to but I'm familiar with what they're talking about. Fair warning, while I've experimented with this, I wouldn't endorse them as strongly as the commenter and don't think I'd use a phrase like 'the shift is real' (unless I was trying to annoy my child).

If I were you, I would start with some documentation:

https://schema.org/docs/gs.html

https://schema.org/SoftwareApplication

https://schema.org/Organization

The first link will get you started - it will explain what the commenter was talking about in detail. The second and third links will give you more information on those specific types.

Good luck with your site!
