Use on my website an audience hasVisitedTheUrl of antoher site on same domain, using Target too

[Tienzen]

Hi

I have got two sites on same domain (site AA and site BB), implemented with Target.
For specific needs, each site have its own AT_properties (different clienCode, different imsOrgId...).

I created a profile script that capture the case a user visited specific group pages on AA.

if (page.url.indexOf('urlToMatch') > -1) {
return true;
}

Then would use this audience (hasVisitedPagesAA) to play an Experience Targeting (XT) Activity on site BB.

Unfortunately, it does not work.

My use case is it really possible to implement ?
If yes, how to make it work ?
