Open onlyoffice on other tab

Is it possible to open onlyoffice in other tab or other window.
when in next cloud try to open a document it’s opening I same window, then need to switch back (back space) to see home or other document. Other problem is you can not open to document at the same time when it’s opening always in the next cloud page.
i have a next cloud on ubuntu and integrated onlyoffice in same server.
