Hi Vimal, I would like to ask if you can find a solution to your question. I have my Macbook Pro M2 too and iMac 27" late 2015. I bought a USB-C to Mini Display Port. Cable Thunderbolt 3, but unable to connect as monitor with command-F2. Thank you.

Sorry that will not work, because those Mac's do not support Target Display Mode.

carefully read > Use your iMac as a display with target display mode - Apple Support

It won't work, please carefully read Target Display Mode. Both devices are WAY too new for Target Display Mode to work.

You can only use older iMacs (2012 and before) with the technique you are trying the only way to do this is to use one of these dongles I have liked the dongle and a set up video below.

If you're referring to Target Display Mode, the last iMacs to have that were the mid 2014 ones (not 2012 ones). Not that this helps the OP. Target Display Mode went away when the first 27" 5K Retina iMac came out in Late 2014, a year before the OP's 27" 5K Retina iMac did. Even when iMacs got Thunderbolt 3 in 2017, TDM did not return.
