Hi All,
Any idea which form is showing when add new portal comment on timeline? Because currently it showing only comment and attach file like below:

If I check on Portal Comment form, the main form design is like below:

My intention here is to make timeline like what example I seen from Creating Consistent Communication Using Portal Comments (meganvwalker.com):

Currently, because I can only put comment and attach file when add comment, it always show my user and my portal name (which should be another user name).

Thanks.
