How to open and edit documents

To open the file in ONLYOFFICE online editors, go to the Context menu by clicking on the 3 dots or click the file name and choose the “Open in ONLYOFFICE” button.

Setting up document permissions

By default, the message sender has edit permission, and all other chat members have read-only access to the file. Only the message sender can change it using the “Change access rights” button in the context menu.

• In one-to-one chat, use the drop-down menu in the Access rights for the @user field.
• In Group chat, use “Default access rights” to set the same access rights for all chat members.

To give access rights to a particular chat participant, enter his name in the search box and click “Add”. The username will appear in the list, where you can set the file access rights.
