Searching google for the current model 3 manual, I get:
https://www.tesla.com/sites/default/files/model_3_owners_manual_north_america_en.pdf
The relevant section to your question is on page 21 & 22. I have copied and pasted the text from that page below, which seems to pretty clearly answer the question.
===================================
USB Ports
Model 3 has two USB ports located in the front compartment of the center console.
These ports can be used to: • Connect and charge USB devices. • Play audio files stored on a phone or USB device (see Playing Media from Devices on page 135). • Save videos when using features such as Sentry Mode or Dashcam (see Security Settings on page 141). The left port is USB-C compatible whereas the right port is USB-A (on vehicles manufactured before approximately June, 2020, both ports are USB-A).
Two additional USB ports are located in the rear of the center console (on vehicles manufactured since approximately June 2020, these ports are USB-C).
These ports charge USB-connected devices but do not communicate with the vehicle.
