@Pierre-vh I am waiting for @arsenm's approval since he opened the issue. But, do you know why I do not have the ability to merge the PR? I do not see the "Merge Pull Request" button. And, do you know if there is something I can do to make the button available to me? That way I do not have to ask others to merge for me? I attached a screen shot of where I would expect to see the button.
