how to create a mac os X mountain lion bootable USB from macos catalina

hello Apple's community

I just acquired a 2010 macbook pro with a failing hard drive, I've replaced the drive and tried to install the OS following this link https://support.apple.com/en-us/HT204904

I'm facing an issue and decided then to buy mac os x mountain lion in the perspective to create a bootable usb stick

the problem is that I'm not able to find the download link of my purchase

I'm using my current macbook pro with catalina

regards

Start up from macOS Recovery

To start up from macOS Recovery, turn on your Mac and immediately press and hold one of the following sets of keys on your keyboard. Release the keys when you see an Apple logo, spinning globe, or other startup screen.

Command (⌘)-R Reinstall the latest macOS that was installed on your Mac (recommended).

Option-⌘-R Upgrade to the latest macOS that is compatible with your Mac. (My recommendation)

Shift-Option-⌘-R Reinstall the macOS that came with your Mac, or the closest version still available.

Apple will sell you a disk containing an older version of MacOS, but you need to have a system on it already.

The problem is you can't download 10.8 installer from a post 10.8 system. You have to do so in 10.6.8 to 10.7.5 Mac App Store.

What you might want to consider is finding someone who has an older system and connect it via Target Disk Mode and install that way.
