Hello @Fábio Miguel Ferreira Coelho,
The the awser from @Harika Ramadalai is almost right.
Just need to change the JS to this:
var objDiv = document.getElementById($parameters.elementId);
objDiv.scrollTo(0,objDiv.scrollHeight);
Also instead of refer to the container by a class is better by an ID. After and this JS, you need to add an input parameter and also link that input to the ID of the container. See this images:


I try to add the OML, but I don't know why, now it have 7Mb and OS have a limitation of 4Mb. You can download from here:
