 - Apply the `searchable` property label to schema properties with stored content that you would like your users' prompts to match against in Copilot. The `searchable` label is the most important with respect to Copilot because it defines which schema properties can be searched against.
 - Add a [urlToItemResolver](/graph/api/resources/externalconnectors-urltoitemresolverbase) in [activitySettings](/graph/api/resources/externalconnectors-activitysettings) when you [create your connection](/graph/connecting-external-content-manage-connections#create-a-connection).
