Is it possible to get a rapid anti-gen Covid test at Mexico City International Airport

Is it possible to get a rapid anti-gen Covid test at Mexico City International Airport?

If so:

• Where is the test center located in the airport?
• Is it open 24/7?
• Do they provide a certificate that is valid for entry in the US (I am a US citizen with proof of vaccination)
• Is an appointment required?

If not:

• Does anyone know of a test location near the airport?

UPDATE: We stayed in the Courtyard Marriott hotel at the airport the night before our early morning flight. There was a Covid testing center right in the ground floor of the hotel. It was around 700 MXN (~ US$35) for a quick test (which provides the certificate acceptable for airlines to the US). No appointment needed. There were other on-the-spot test centers in the airport, probably cheaper.
