Enable Apple Music on iTunes I'm unable to activate Apple Music on iTunes 12.7

When I go to Preferences -> General There is no Show Apple Music option.
Apple music works fine on my iPhone.

How do I enable Apple Music on iTunes?
The solution was to go to Account on the top bar and then click Authorisations-> De-Authorise This Computer and Authorise again.
After this the Apple music will be shown in iTunes Preferences.
