[Vortex] pull api + vortex_event_get_profile_content

[DEXTER]

Hi,

Using the pull api, at the channel start event you have only one
function to get the profile_content.
Although this function only returns the profile _content_ not the
profile itself.
The question is, how one can set the profile content, or how one can
get the actual profile uri instead of this unknown profile_content
string?
(which is always empty)

thx.
