Im working on a project with two apps, one for the client and one for the provider. Everything has been working fine, I can chat between them, create events too... but im trying to set notifications on these actions and I can't set a notification on the client app to reach a recipient in the provider app (and viceversa). When I try to select a recipient it just gives me the Document ID option in red, if I try with another user from the same app it works but that doesn't help. How can I trigger notifications between users from different collections? maybe there is a way to trigger a notification when a new document is created in a collection? That way I can trigger one inside the same app as the recipient.
Thank you in advance guys
