On a Macbook Pro (born 2017) in PAGES application: How many times can I use the Undo Command to get back text that was accidentally deleted?

In a PAGES document, I accidentally deleted text I needed to keep that is nowhere else in my document, after which I had made many changes to a list I keep which includes screenshots, numbers and dates, plus having to tell the document to keep the images on the same page with their text, so the images do not go sliding around while I'm typing or adding other images, dates, etc. I cannot find this info anywhere, but it must be available if there is a FINITE number of times the "UNDO" command, which is also Command-Z.
