Bunq integration, need idea

Hi there
I am looking for implementation ideas…
I am creating a custom_component to integrate with bunq.
Currently I use sensors to display the balance of accounts.
Now I would like to be able to display the last 10 transaction of a specific account and I am not sure about the approach.
I thought of creating a sensor with a json representing the transaction as value. Then I would need a custom Lovelace card to display the result. Or maybe I could use another kind of entity?
Any idea are welcome… Ideally I would like to avoid creating a custom Lovelace card.

Thx
