[WebDesigner] Filter on candidate Objects using logged user in the request

Hello,

I am trying to use a function inside the Filter on candidate Objects on a table property in a Component in the Web Designer , and I am getting a SyntaxError

This is my non working filter:

"UID_Department IN (SELECT UID_Department FROM Department WHERE (CustomProperty01 = '06' and 
(CCC_AE IN (SELECT UID_AERole FROM PersonInAERole WHERE UID_Person = GetUser() ))))"

Could you please advise on how to get the logged user UID_Person inside this request

PS: the filter below is working if I replace GetUser() by a uid

"UID_Department IN (SELECT UID_Department FROM Department WHERE (CustomProperty01 = '06' and 
(CCC_AE IN (SELECT UID_AERole FROM PersonInAERole WHERE UID_Person = 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx' ))))"

Regards,
