How to send Slash Commands to Slack

Hi people
anybody know how i can send slash commands from node-red to slack?
i need to invoke a "/pool" for example in Slack
i have a integration between WA <> Node-red <> Slack and i need analyze the responses from WA in Node-red and decide between send a direct response to user or make a pool in a slack channel

Yo don't mention which slack node you are using - but no matter - you may be best trying to contact the author direct. I would expect it should just work - but you may need to escape the / somehow. maybe try another / ?
