Adding audit to Projects module

Hello Developers,

i need to audit (view change log) the "Status" field in the Projects module.

i noticed that the Project module doesn't have an "View Change Log" button at the top of the Detailview, when all other modules including custom ones i created, does have.

i also noticed that the fields in the Project module, in the studio, DOES have the "Audit" checkbox to check.

but where can i watch the "view change log" if i don't have an audit button at the top of the detailview?

if i can't view it, how can i add the "view change log" button to the top of the detailview ( i familiar with the code of Sugarcrm)

Using Sugarcrm Community 6.5.13

Thank you!
