How Do I Use an iMac 2010 (Yosemite) As External Monitor for MacBook Pro (2022)?

I have a MacbookPro from 2022 with Ventura and I would like to use my iMac from spring 2010 (Yosemite) as an external monitor for my MacbookPro. Is this possible and if yes what do I have to do to make this work? I tried connecting the two computers with a cable (Miniport for the iMac and HDMI for the MacbookPro) and then pressing “Alt F2” on the iMac but this did not work.
I do not use the iMac as a computer anymore but I would like to use it as an external monitor as the monitor is still very good.
