Coviu allows for files (images or PDF's only) to be shared within a Coviu call.
To access the Share a file tool in a call, you'll need to go to the top right corner of your Coviu call - you will see a Tools button.
Click on 'Tools' - you'll be shown a list of available tools to be used in call.
Next, click on 'Share an image or PDF' -
Now you can share an image or a PDF during your Coviu call. Any data shared in a Coviu call will not be stored. Once you leave the call, the data will disappear too. Should you want to save any data, you'll need to manually download the files out of the call, before the call has been closed.
