Unable to export library to protected model

I have created a library which I need to protect in order to ship to my clients. Following this tutorial, I tried to export my library model to a protected model. However, I am unable to see any option for the same.

If I try to export a regular model, I am able to see the option to export the model to a protected one

The first image shows the save options for a non-library model, and the second one is for the library model (both are .slx files)

I also checked if I have Simulink Coder installed, and while I can see the name in the list of installed packages, running

license('test','Simulink_Coder')

returns a 0 indicating that I do not have the license. But in that case, I should not be able to export a non-library model to protected model either. What could be the issue and how do I solve it?

Before investigation, license string for Simulink Coder is "Real-Time_Workshop". Can you re-run the command below?

license('test', 'Real-Time_Workshop')

Yes, I just ran the command and received the output as 1
