Modify Custom Labor Distribution Accountant role

Hello everyone,

We have created a custom Labor Distribution Accountant role. There is a business request to remove access to "Create" on the Manage Labor Schedules tab and "Process Costs" on the Manage Labor Costs tab. Please see the attached for screenshots of the request and custom role set-up.

Could anyone assist us on the best way to modify this custom role to ensure that these permissions are revoked? Any detailed steps or insights would be greatly appreciated.

Thank you in advance for your help.
