Change Management tab is not available in ChaRM Project

Hello Experts,

Need your help.

I need to perform some configuration and for that I am working on Sandbox system.
Now the problem is, Change Management tab is not available in my Project (in Solar_Project_admin). Please find attachment.

I have created a new Project as well but got the same issue. Even in newly created project, Change Management tab is not available.

Can you please help me in this?
Can you please tell me what could be the reason behind it?

Thanks

Gaurav Patel
