Hello,
I looked into steps for integrating Linkedin Sales Navigator with Dynamics 365 sales pro. But when I tried installing it from the appsource it asked me to select an environment. I did not have any environment, so I created new environment. Yet it still did not allow me to install. Option 1 which is installing through advance setting is not working for me, as I could not find the Linkedin Sales Navigator option in it. There is also no app setting option in my Dynamics 365 sales pro.
