Hello, this is Emily.
When you had your XPS from 2022, did you redeem the Office that came with your purchase? By the way, it should be either home, or business, not AND.
If you have redeemed it, you can go to www.office.com, sign into your Microsoft account you used for redeem. Once signed in, you should see the option to "install office apps" on the upper right. Click on it and you can download the installer to install the suite.
If it is a business version, you will need to sign into a business account, not a personal Microsoft account. Such business account is either your custom domain email address, or one using Microsoft's default business domain @businessname.onmicrosoft.com. I think most likely yours is the home version as it is unlikely that Dell offers the business version.
See if that works. If not, you might have to contact Microsoft support with proof of purchase, with which, support can reassign you the license. https://support.microsoft.com/en-us/contactus
