Social Connection to Facebook & Instagram

We have a website on WordPress.com with a Business account. I am looking for some guidance on connecting our site to Facebook and Instagram. The Facebook page is using the ‘New Page’ experience and is managed in the Business Manager. Reading a different post and the Jetpack Social documentation on this it appears that I can’t use this page with Jetpack Social.

However, we do use it. To do so I have to supply Jetpack with my personal Facebook login. I set up the Facebook page and am a full admin of it and the business account. When I put my personal Facebook credentials into Jetpack I can choose among a few Facebook pages I manage, one of which is the page in question.

I’m glad we can use it. I assume that this works due to something I don’t understand about Facebook Pages. I really don’t understand much about them.

Is this a completely undocumented way to connect that I have stumbled upon? If it is not can someone explain to me what is going on so I can set up additional users on Facebook so the other folks on my team don’t need to have my Facebook password?

Thanks for any help
