Working on a PDF File simultaneously from 2 PC's or more

Hello together,

i know office 365 and there you can write in a word document sumultaneously from 2 or mor PC's.

So if i'm in Germany and my co-worker is in the USA, he hass the document open, i have the document open, he can write, i can write, he can see what i'm writing, i can see what he is writing, he can save the document and i can save the document too.

Is there an option to do this with a PDF?

I'm simply searching for a function, where 14 people can make notes in a PDF file at the same time.

Actualy, person A open the PDF, write a comment, save the PDF and close it.

After that person B can open the PDF, write a comment, save the PDF and cloe it.

And so on....

Thx for your help.
