Run Two Computers to Thunderbolt Monitor

I have a MacBook 14" 2021 M1 chip connected to a Thunderbolt Monitor via a Thunderbolt 3 (USB-C) to Thunderbolt 2 cable.

I also have a iMac 24" 2021 M1 that I would like to connect to the same Thunderbolt Monitor so both the MacBook and iMac can work on extended display to the Thunderbolt Monitor.

Can this be done?
