Good catch! bringing the same approach to Financial Connections.

+                resultCallback::onResult
+            )
+
+            return remember {


Should this be keyed off all of the input parameters? So that in case a different instance of any of those parameters are provided on a subsequent composition, a new instance is returned using those new values.

return remember(config, readyCallback, resultCallback) { // ... }

I think the same question would apply to the other rememberLauncher methods also. (I could be wrong – still a bit of a Compose novice!)

I'm also pretty new to Compose. You're partially right, I've updated the example to use the config as a key. For the callbacks we use rememberUpdatedState, which is also what rememberLauncherForActivityResult uses. I added you to the API review doc, ptal and let me know if you have any suggestions.
