Hello all
I am rather new to Portals, so please bear with me if i am missing something obvious.
I am struggling with the functionality of the timeline in the Portal side on the entity "Case". I want to show a timeline with portalcomments for the user on Portal, but right now it does not show anything. I have created a entity form with the following settings:

Furthermore, i have enabled the timeline on the Form "Test" and set it to show activities.
In addition to this, i have added entity form metadata as followed:

When i then try to see it from the Portal side, it just says "there is no activities to show". In CRM, it is showing all the different activites on the cases.
I have no problem with showing "notes" with the timeline in Portal, but as soon as i change and trying to display activities nothing is shown.
I do not known if it has anything to do with the entity permissions. I have the following relevant active (which i think is some standard permissions from Microsoft side):

As i understand this should be standard functionality with the entity case, but i can not figure out what i am doing wrong.
I hope someone can help me or point me in a direction where to look.
thank you in advance
Best regards,
Casper
