How can I enable the succession plan for managers without enabling the 'My Client Group' tab?

Summary:

Line managers would like to create their succession plan, and we want to ensure that only the HR team can see the icon under My Client Group. Our objective is to enable this feature for line managers without enabling the 'My Client Group' tab for them.

We would like to enable the succession plan for managers while keeping the My Client Group tab disabled for them. Currently, when we assign the role 'ORA_HRM_SUCCESSION_PLAN_DUTY' to the line managers, the system automatically enables the My Client Group tab and additional features for them. Although we are adding an icon under the My Team tab, the My Client Group tab remains visible. However, we cannot create a rule to hide the My Client Group tab specifically for line managers, as we have some managers with HR roles who require access to the My Client Group tab.
