How to enable the internal/external visibility toggle in a customized entity?

[dgiovannetti]

Hi everyone,

I'm trying to figure out a specific configuration in customized entity and could use some help.

I need to configure an entity so that its activity stream includes the visibility toggle. Specifically, I want users to have the option to make a stream entry visible to third parties, or keep it preserved internally (indicated by the red padlock icon).

I know this functionality already exists, as it's currently active and working perfectly in the Support Tickets / Cases stream.

Could someone point me to the exact setting or the steps required to enable this same visibility/padlock feature for other entities?

Thanks in advance for your help!

allowInternalNotes parameter set to true in clientDefs

Note that starting from v10.0 this will get moved from clientDefs to streamDefs
