Hey there @robdavey555!
Terribly sorry for such delay in response but I must have overlooked the whole queue and didn’t find it among other topics. Let me get back to the core topic.
So the thing here is that you should use the value after the | sign (without the auth0 at the beginning) which you claim you have tried. In the latter one you mentioned everything should be right there.
If you haven’t handled that in the meantime can you open a GitHub issue in appropriate repo and then share the link here so we can work on that directly with the tool maintainer? That will be the most effective way. Thank you!
