Looking for Mojave iso or dmg Installer

Figure that someone on here may have a .dmg or .iso for Mojave as that is what we use when we run Pano Classic. If you could private message me, that would be great.

This support page should allow you to install Mojave via the App Store.

I’ve tried that and every other ‘legit’ path and the all end up with dead ends.
Apple’s links either just offer the Update or are blank pages. I need the ‘non-Update’ to install on an older computer. They all want to install Catalina. I’ve erased the disk after an Option-Command-R to start empty, yet they all only let me install beyond Mojave which Pano Classic requires.

I may have to load from a Time Machine backup but that is being problematic as well.
