Installing Mojave on a separate volume

I have a MacBook Air, early 2020, running Catalina (10.15.7). What I'd like to do is to install Mojave on a separate volume on my SSD so that I can run some 32-bit games that are incompatible with Catalina and Big Sur and are unlikely to be updated. I believe, reading some other posts, that I can install Mojave from a bootable USB flash drive. However, when I try to download the Mojave installer from the Mac App Store, I get a popup telling me that this version of macOS is not available.

Is there a way to download the Mojave installer so that I can set up a USB flash drive as a bootable drive with which I can install Mojave on a separate volume? Thanks!

It is odd, but for me, when I go to to the bootable USB page --> https://support.apple.com/en-ca/HT201372 and click on the download link for the appropriate version (in your case macOS Mojave) using the App Store link after going through that series works for me. Get macOS Mojave.

It took me to this screen, https://apps.apple.com/ca/app/macos-mojave/id1398502828?mt=12, which opened the download.

TL;DR

Bootable USB Page > "Get Download Link" > "App Store Link" > Wait for it to load

Those are exactly the steps I followed. Once the App Store link loads, I see the Mojave description in Mac App Store. There is the "Get" button on the upper right of the page. I click that. Then System Preferences opens and tells me: Update not found. This version of macOS is no longer available.

What am I missing?

Thank you for your efforts to help. Perhaps there is some setting on my Mac that is different than yours that I need to change in order for this to work. If someone else has run into this issue, I'd appreciate hearing from you!

I apologize as I am no longer able to help you. I cannot seem to figure out what may be wrong. Going through each page was what worked for me when I experienced the same issue.
