I'm trying to access chatter in visualforce using iframe in customer portal.
Reason why I'm not using the default chatter tab is because I'm adding some custom styling in visualforce and I also don't want to see the sidebar and header.
The iframe works under force.com but when trying to access through community it throws an error page

<apex:page sidebar="false" showHeader="false" standardStylesheets="true" doctype="html-5.0">
    
        <apex:pageBlock >
           <apex:iframe id="iframe" src="/_ui/core/chatter/ui/ChatterPage?isdtp=vw" 
                        scrolling="true" width="100%" height="500px"/> 
        </apex:pageBlock>
        
</apex:page>

Can somebody help me understand why it does not display in community?
