[GEphrau]

🔖 Feature description

You should add the possibility to specify some additionnal data for a workflow step that use expo

🎤 Why is this feature needed ?

Currently i can only specify additionnal data in the payload while triggerring a workflow. In my case i would like to send some specific data per worflow step that use expo. The value for data could be different from a step to another one.

✌️ How do you aim to achieve this?

I would like to have an additional input on the workflow step edit page, to add the data field for expo notification.
