This is what Slack really screwed up. We use 12 different meeting tools, it's absurd I know, and if Slack worked it would be great. You start a chat and you can't add someone to the chat once it's started. So you create a new chat and add a member to it. Now you decide to hop on a call and you need to invite someone else, and that wasn't an option. But today, you can add another team member to the call. You figure out it's a vendor issue but you can't get your vendor on the call because they don't have a Slack account, and there isn't a link to share for just that one screenshare/conference. So you are left with inviting your vendor into your Slack space which you don't want to do or move to another solution.
