Welcome to the Atlassian Community!
You will need to add those people you want to your Jira and give them access (which chews up a licence for each one)
At the moment, your Cloud site is hooked up to an identity provider that does not have the emails of your customers added to it. You'll need to talk to your user managers to get them added.
