Node-red-contrib-dutch-weather Trigger

[Nice_to_have]

Goodday everyone,

In the description of node-red-contrib-dutch-weather it says that the node needs to be triggered in order for it to work.
*Quote: *
In order to get updated data you have to send a message on the input of a node with payload { trigger: true } for it to update.

I am not sure what to fill in here.
Can someone advise on what I am doing wrong?

You would put { } around the and use quotes for valid json
{"trigger": true}
