Multiple Instance H5P


I would like to know if is there a possibility to run two Lumi H5P files at the same time, in order to copy/paste a part/item of courses easily.

I have seen that a server exists, which could be able to do this if I understand correctly. In this page :

What could be the best way to have the possibility to work on two instances in the same ubuntu session, if it's possible ?

PS : I use the copy / paste integrated in Lumi, but it requires to navigate between the tabs, which is already very good. I'm looking for a way to have these tabs in different windows.


Thanks a lot,
