shopify email app link with custom app trigger flow

[akashmakkpress]

i've query about the Flow/Triggers extension in app, i've created an wallet app that stores the customers wallet coins and i want to implement the flow trigger , if more coins are added to customer wallet from app backend. then by flow trigger it should send the email to customer of new coins are added by shopify's email app, so we need to connect our app created flow triggers to shopify email app. So that email will shoot by email app. How can i do it ??
