Third monitor is not detected

Hello! I have a MacBook Pro (13-inch, M1, 2020), Monterey 12.6.1. I also have to monitors. One is rather new and I connect it using USB-C port. Another is quite old and I connect it using a VGA cable and a VGA-USB-C adapter. When I connect them one by one there is no problem. But if I try to connect both of them, then the second one that I am trying to connect (could be either of them) is not detected. How can I sold this issue?

Thank you!

There is no issue. The M1 Macs only support one external monitor.

Here are the specs: MacBook Pro 13-inch - Tech Specs - Apple

"Simultaneously supports full native resolution on the built-in display at millions of colors and:

One external display with up to 6K resolution at 60Hz"
