How do you pull Revenue data from Facebook connectors?


I'm trying to create a marketing dashboard for my company that looks at revenue, spend, ROAS, etc. I am able to pull spend and a value for ROAS, but I can't seem to find the variable for revenue. I know Facebook usually refers to revenue as "purchase conversion value" but I can't find that variable when selecting the dataset. There is a variable called "conversion values", but when I attempt to include it doesn't show up in the dataset. To be honest I'm pretty new to using the DOMO connectors and it is very possible I am just not trying the right method for pulling the data. Does anyone have any answers for how to get revenue data from Facebook?
