Is it possible to have a workflow post as the person who used the workflow? I do see that I can add the person who ran the WF as a mention in the message posted, but I'd prefer the post itself appear to come from the running user.

Hi @Timothy Sheehan​ -- good question! The workflow will indeed need to post as the workflow itself (as the "app"). A solution here could be to perhaps have 'header' text that is bolded, saying who the content is from. Unless this person is the only person posting/running the workflow? If that is the case,perhaps you can edit the workflow settings and make the image icon their photo and then label the workflow as their name. But if more people than just them are using the workflow, that wouldnt work. Sorry I don't have a better answer here; hopefully the workaround will help! 🙌🏽
