Talk meetings on shared nc office files with guest cannot be performed

Hi there,

my actual versions are:

• NC 29.0.7
• Talk 19.0.9
• NC Office 8.4.6
• Share settings: allow

Description / steps to reproduce:

• create a new e.g. presentation

• press the share button directly at the presentation creation / modify screen and select Chat
  

• as described you have to share the presentation before you can discuss it -> share the presentation to a guest per email invitation

• allow the guest to edit the presentation

• click on the link at the invitation email

• the browser opens, for a second you can see the regular view same as if you share files and on the right side there would be the chat part but the browser changes to the next screen where the presentation opens in nextcloud office

• at this stage you cannot chat with anyone other -> there is no chat part and you cannot open talk or chat

The thing is that you want to discuss a presentation with a guest, you share the presentation but then you cannot use talk.

If you close the presentation, the chat view will be visible:

and you can open the chat part -> you have to enter a name. Now you are in the chat part but cannot modify the presentation together with someone else.

How can the system be configured to allow talk meetings during a collaborate file creation / modification with guests = no nextcloud user.

Thank you,
Stoneubi

Start by reproducing the reported flow with the listed Nextcloud, Talk, and Nextcloud Office versions: share a presentation with a guest, open it from the invitation, and verify whether Talk is unavailable while the document is open. Compare this with the chat view after closing the presentation; done means guests can participate in Talk while collaboratively editing the shared file.
