How can I export a Chat GPT file from my iPad to my iMac?

How can I export a Chat GPT (Free Version) conversation from my iPad to my iMac to allow me to print the file.It is a bit too big to use repeated screen shots,

I have tried copying the entire file - about four pages - and using Airdrop but this doesn't seem to work.

For some reason I have been unable to email the file.

I have done this successfully on a couple of previous occasions six months ago but I am now quite unable to replicate the process.
