Is there a plugin get an message in Libre or MS office that a file is under processing? Because if some people edit some MS-Officefiles they will not be notified if the file is already opened by someone else. We using here Nextlcloud 15.xx.

So how can we enable the feature that nextcloud deteced that a file is under processing? The documents are to complex that we are not able to use Collaboara Online.

Very Thanks and best regards
