let userData: any;
try {
    const localStorageUserData: any = localStorage.getItem("user");
    userData = JSON.parse(localStorageUserData || "{}");
} catch (error)
const abilities = RBAC.hasAccessFor("member", _.get(userData, "data.role", {})

//eg.Method for user access check
const checkUsrAccess = () => {
    return (
        abilities.can('create', 'userRoleManagement.userAccessPermissions.roleAccess_1')       ||   //returns true
        abilities.can('view', 'userRoleManagement.userAccessPermissions.roleAccess_1')         ||   //returns false
        abilities.can('update', 'userRoleManagement.userAccessPermissions.roleAccess_1')       ||   //returns true
        abilities.can('delete', 'userRoleManagement.userAccessPermissions.roleAccess_1')       ||   //returns false   
        abilities.can('create', 'userRoleManagement.userAccessPermissions.roleAccess_2')       ||   //returns false   
        abilities.can('edit', 'userRoleManagement.userAccessPermissions.roleAccess_2')              //returns false  
    );

        "role": {
            "isSuperAdminPermission": false,  // [true  - overrides role checks to true.] 
                                              // [false - checks individual role permissions]
