My 2020 M1 MBP (Ventura) recognizes and can extend its monitor to my 2021 M1 iMac (also Ventura), but my iMac won't extend onto my MBP. Shouldn't screen extension work both ways? My only option with the iMac is to link the keyboard and mouse to the MBP.

Hello jcw289,
You can double check the continuity requirements with the article here: System requirements for Continuity on Mac, iPhone, iPad, and Apple Watch
However, as it lists an iMac introduced in 2019 or later double check your preferences with the steps below found here: Set up your Mac to be an AirPlay receiver
"Note: If your Mac is enrolled in a mobile device management (MDM) system, AirPlay Receiver may be unavailable.
> System Settings, click General 
in the sidebar, then click AirDrop & Handoff 
on the right. (You may need to scroll down.)4.Turn on Require password, enter the password in the text field, then click OK."
If the issue continues, you can test in a new user account. Add a user or group on Mac - Apple Support
Reach out to Apple Support directly if the issue remains.

Hello jcw289,
Thank you for reaching out to Apple Support Communities.
If your Airplay isn' working as expected, try these helpful steps:
"Try these steps first
After each step, see if you still need help.
If you're prompted to enter a password, you might have restrictions turned on, or you might need to adjust your AirPlay password settings."
More details can be found here: If screen mirroring or streaming isn't working on your AirPlay-compatible device
If the issue persists, can you provide a few more details? What is your exact macOS versions on both devices? Also, has Airplay worked previously?
Cheers!
Since Airplay works in one direction, yes, they're turned on, near each other, on the same wifi network, no restrictions are turned on, and both devices are using the most recent OS, 13.2.1. As noted, I can extend the MBP onto the iMac, but not the iMac onto the MBP. In fact I have two MacBooks, and can extend the iMac onto my M2 Air (although screen resolution is poor), but not onto my M1 MBP.
Embarrassingly, this solved the issue. Thank you OrigamiFan, I was unaware of that setting.
regards.
