Trial of MS Intune - Device not in Intune

Hello, i have setup a trial of MS Intune and setup a user and placed this user in a group in inTune.

I have followed KB https://docs.microsoft.com/en-us/intune/fundamentals/quickstart-create-user

Then https://docs.microsoft.com/en-gb/intune/fundamentals/quickstart-create-group

I did not want to setup automatic enrollment for windows 10 devices as i have only a single machine that i want to enroll at the moment. on

https://docs.microsoft.com/en-gb/intune/enrollment/quickstart-setup-auto-enrollment

then i enrolled this single machine

https://docs.microsoft.com/en-gb/intune/enrollment/quickstart-enroll-windows-device

However the user connects fine, but i do not see this machine in InTune Device Enrollments

I guess the automatic enrollments needs to be added?

But im just concerned being a new person to this that i do not want all others windows 10 machines i have at the moment to be enrolled.

Is this the case?

Thanks
