Find Kindle book on Macbook Pro - macOS Sonoma 14.6.1

I would like to download my Kindle books purchased from Amazon to my laptop in order to convert the books to a pdf. However, I cannot download the Kindle books from my Amazon account nor my Kindle App on my laptop. I also cannot locate the Kindle books I have purchased on my laptop in order to download so I can convert them to pdf.

My questions to everyone are:

• Is it possible to access my Kindle books on my Mac?
• If I find my Kindle books on my Macbook Pro, is it in a format that I can use to convert to a downloadable format?
• Is there an application that can convert Kindle books (from Macbook Pro) to a pdf?

Please feel free to ask any clarifying questions (I'm certainly not an expert :) Many thanks!
