[Forums] In-App Notifications Core: add a parameter for Sender

Hello Adrian,

Thank you for the feedback. 

Actually, you don't need the parameter. One of the current parameters of the SendNotification Action is the "Notification". This parameter receives a structure, and in that structure you have a field just for that.

However, there is a bug in the API, and that parameter is ignored.

We will add a fix to this issue in the next version of the component, to be released soon.

Cheers,

Samuel Jesus
