Hey CCIA
You'll need to invite the user directly from the company file itself. If you're in the desktop you can do this by selecting Setup > User Access from the top taskbar.
If you're using the browser this can be done by clicking the settings cog on the top right and selecting Users and permissions.
We recently announced that we are retiring my.MYOB, more information can be found on this page. If you use my.MYOB to manage users (like you have in your screenshot), this can now be done directly from your company file. We have published step by step instructions on this page, you'll be able to toggle between desktop and browser depending on what you're logged in on.
Hope this helps, feel free to reach out if you have any further questions.
Cheers, Amanda.
