How do i see conversions in FB ppc reports?

I have created a campaign in facebook PPC. I have also created one custom conversion , which basically triggers when someone complete sign up process. But, fb ad campaign reports, I dont see any "conversion" column. I was hoping fb will tell me, how much money i spent and how many conversions i got.

I am using conversion campaign with facebook messenger as end goal. So, I want clients to talk to me on messenger.

what am I missing?

Which marketing objective did you choose? And also, have a look on the Ad Set Level, at the bottom for what you optimized (pay for)

But basically, you need to click on customize columns

Install the Facebook Pixel.
Choose Which Standard Event Actions to Track.
Install the Conversion Code on Your Website.
Confirm the Tracking Is Working.
Use Custom Conversions to Split Standard Events.
Add Conversions to Your Reporting Dashboard.
