What does this PR introduce?

Hey @drwlrsn, thanks for your contribution. If you merge main branch the vercel deployment should complete successfully.

Hi @drwlrsn 👋 has this work been abandoned? We're looking at using react-live-chat-loader with HubSpot too, so the work that you've done would be useful to us as well.

[drwlrsn]

Hey! @mariuszkosmatka the company I was working for when I whipped this up no longer exists and so neither does the need for it. But, I'm sure we can get this over the line. You might end up being the first (again) using it in production.

Hi @drwlrsn -- I'd love to be able to make use of this too! Thanks for your work here. I'll be following to see if it gets merged.

Following this work on https://github.com/calibreapp/react-live-chat-loader/pull/281 as I don't have permissions to push to that fork. Let me know if I'm missing something
