Tinshed: Hmmm, with Chrome Remote Desktop it seems that each time you want to share your screen, you need to give the access code to the person who wishes to access your computer. This won't work for the "elder support" I am sometimes required to give. Quite often I get the "Mum's computer not working, can you fix it? She has left it running." question and the beauty of LMI was that I could do that without any intervention on her part. Might try Teamviewer. Or have I misunderstood something?
The code is needed for one-off access. You can just configure the PC to always allow remote control, and that will be permanently linked to your account.
