Need to create Rule for opportunity in SAP C4C

Dear Team,

Could you please help to create one rule for requirement "If the opportunity status is Set as Won, business role sales executive should NOT have access to add any involved party under the opportunity".

Please find below rule which i have created but 2 conditions are not working together.

IF(AND(MYUSERROLES()!="SALES_EXECUTIVE",Root.LifeCycleStatusCode!="4", true, false))

Thanks and Regards,

MD.
