I am trying to extract campaigns containing 2 different strings:

var keywordSelector = AdsApp.keywords()
 .withCondition("CampaignName CONTAINS_ANY ['Apple','Orange']")

I am aware CONTAINS_ANY operator works with labels only, so what would be the operator for campaign names?

something similar to IN operator that can extract multiple campaigns matching exactly:

var keywordSelector = AdsApp.keywords()
.withCondition("campaignName IN ['S_Apple_EX', 'S_Orange_EX']");
