Downloading Analysis ToolPak

[AlliMarieee]

Hi everyone, I am having trouble downloading the Analysis ToolPak in Excel through Microsoft 365. I have a MAC late 2016. When I looked further online it said to go through the Tools menu and click the add-in tab. My screen doesn't give me that option, so I tried through  File-Options- but then it only gives me the option to change Regional Format Settings. I really need these tools for a lab that's due in two days so I would really appreciate any help.....Thank you in advance...
