MATLAB Simulink support packages for ST MCU's

[VVija.1]

In MATLAB Simulink 2020b Software, I saw that support packages are available for STM32 F4, STM32F746G, STM32F769I; But in this document, "https://my.st.com/resource/en/data_brief/stm32-mat-slsh-target.pdf", it is mentioned, the following controllers are added, STM32F302xBxC/STM32F303xBxC, from where can I download package for this controller,

What are the other micro controllers supported for MATLAB Simulink
