S2722QC, Display Manager for Mac (OSX)

I am looking to get the Dell Window Manager set up on my Mac Book for Sonoma 14.4.1. When I install the software, it said there was a newer version available, which I checked for. While that was working, the software crashed. I think the new version was actually the Dell Display and Peripheral Manger, which seems to have overwritten the Dell Window Manager software. Now all I have is an icon on the Menu bar with a screen with a gear in it and a caution symbol in front of it.

When I click on it, I get the message below:

One of the reasons I bought this monitor was to use the Dell Window Manager, which appeared, at the time of purchase, to be available for Mac. How do I get this working so I can use the window manager software?

Thanks for the help!
