Notification icon appearing in Citrix Session

Hello,

We use Remote Desktop Manager and Password Manager as a published application in Citrix Xenapp 6.5.
We often see in the connexion center of the Citrix Receiver client a new application called "notfication icon". (see attached file)
This application relate obviously to RDM and PVM but we can't find any way to make it disappear.

Each time it appears, we loose the focus on RDM or PVM published application (even though we are working on a rdp client session for instance).
Could you tell me how to disable the underlying function ?

Thanks a lot.
