I've browsed a ton of threads on here about creating a button to start a list workflow, but not a site one in O365. When I go to the Site Workflows area and copy the URL of starting the workflow I want, I get this Javascript:
javascript:StartWorkflow4('26220e76-0c13-4c07-8763-4f51589b57cf', '', '')
I can't figure out how to basically build a URL or a button to start this darn site workflow. I am not looking to put this on a Nintex Form, just on the page.
