Screen sharing privacy permission missing on a Mac Catarina

I am trying to install Parallels Access and when the installation takes me to the Security and Privacy system preference I am able to select all the Parallels requests apart from the screen sharing request. No entry appears in the screen sharing system preferences for Parallels. I tried installing Parallels Access again but no change.
Any ideas?
Thanks

 

Hi, could you please provide us with the screenshot of the system preferences that you got?
