Hey everyone - I received a transaction a few hours ago, that is still unconfirmed. The person that sent it opted for a pretty low fee - 21 sat/b - is there any way to check if the transaction depends on a previous unconfirmed transaction?

I mean I know it can be done, but how do I do it exactly?

The transaction ID is defa67a4595348f0cb1387104d8cccca755a88d327717a36496f5be9ee6c2f31 .
