I've got a 2020 MBP running Catalina, and a 2013 iMac 27" running Catalina. I have a USB-C hub for my MBP that has a HDMI port. Is it possible to use a Thunderbolt 2 to HDMI cable to connect the MBP to the iMac in target display mode? Or do I need the expensive Thunderbolt 3 to Thunderbolt 2 adapter from Apple plus a Thunderbolt 2 cable?
Thanks.

It gets worse. Your 2020 MacBook is not supported for Target Display Mode, even if you had the right cables.
You can connect any of these older iMac models to another Mac from 2019 or earlier for use as an external display.
TDM has been deprecated.
Please refer to the following Apple Support document: Use your iMac as a display with target display mode.
The applicable requirements preclude using TDM on your Macs: "Make sure that your iMac is using macOS High Sierra 10.13.6 or earlier. You can't use target display mode with later versions of macOS, or with Boot Camp and Windows."
Target Display mode with HDMI cable?
