Simulink - Code Generation Tab is not available

I have MATLAB R2018b, I can't Generate a code since there is no code generation tab,

although I have all of these toolboxes

>> license('checkout', 'RTW_Embedded_Coder' )

ans = 1

>> license('checkout', 'MATLAB_Coder' )

ans = 1

>> license('checkout', 'real-time_workshop' )

ans = 1

I have the same problem. I also have the following installations:

>> license('checkout', 'RTW_Embedded_Coder' )

ans = 1

>> license('checkout', 'MATLAB_Coder' )

ans = 1

>> license('checkout', 'real-time_workshop' )

ans = 1
