finding issues prorated credits (test charge)

Shopify Discussion
1

i have cancelled a test recurring subscription on my development app using the graph ql docs https://shopify.dev/docs/api/admin-graphql/2024-04/mutations/appSubscriptionCancel?example=Cancel+an+app+subscription+on+a+shop+and+issue+prorated+credits#top

mutation AppSubscriptionCancel($id: ID!, $prorate: Boolean) {
appSubscriptionCancel(id: $id, prorate: $prorate) {
userErrors {
field
message
}
appSubscription {
id
status
}
}
}

i have succesfully cancelled the subscription through this but where do i find the issued prorated credits, i know its a test charge but how do i ensure if proration has happened? i cant find any test credits issued in my shopify dashboard. Please help
