Hello people of Mexico!

We are organizing a sponsored fitness event in Mexico City's public parks. We were informed that a government or park facility, possibly associated with a truck handles event coordination. We need to contact this team for approval to use a park space. The city stated we don't need a permit but must speak to this specific team, we're seeking guidance on how to reach them or if there are alternative steps we should take. Our event is nonprofit, focused on community health, and sponsored by various organizations, so it's free for participants. If anyone has information on how to connect with this park facility team or can suggest another approach, we would greatly appreciate your assistance. Thank you!
