Can't copy outside text into OnlyOffice on mobile

### Description

OnlyOffice allows pasting content from outside the tab only using CTRL+V (as opposed to right click>paste). This prevents users from being able to paste content on mobile devices.

### Steps to reproduce

1. Open OnlyOffice app (e.g. Document) on mobile
2. Copy text from another tab
3. Try to paste the tab into OO editor (long press>context menu>paste)
4. A modal appears explaining pasting into OO can only be done with CTRL+V

On Android, a possible workaround is to use Gboard clipboard.

### Relevant logs

```shell

```

### Expected behavior

Pasting into OO apps should be available on all devices, including mobile.
