I have an Office 365 Pro Plus E3 license but can't access new functions in Excel

[LGalves]

I have a desktop version of Office 365 Pro Plus E3 license. I want to be able to take advantage of the new functions that are available in Excel such as XLOOKUP, UNIQUE, etc. but they are not available in the version of Excel that I have. I have chatted with both Microsoft Live through Teams as well as my IT dept and I can't seem to get to the bottom of what I specifically  need to ask for

so that I can take advantage of these new features. Any ideas are appreciated.

Repair an Office application (microsoft.com)
