ECID value to be sent to Adobe Analytics

Hello team,

Earlier with appmeasurement, we used to send Adobe analytics the ECID with "D=mid" to one of our eVars.

Now with WebSDK, Adobe recommends we use alloy send if we have to use it on client side:

return alloy("getIdentity")
.then(function(result) {
console.log (result.identity.ECID);
_satellite.setVar("mcid", result.identity.ECID);
});

So i use aboe code, but this code always runs at the last even if the rule has priority 1.

Do you have any other recommendations on how can i send ECID to Adobe Analytics?

Thanks,

Nitin
