Version 2020.03.04 is available in the upstream git repository:
https://github.com/dropbox/nautilus-dropbox/tags

It would be nice to have this version packaged.

Hello,

Please update nautilus-dropbox to 2022.12.05. It supports nautilus 43+ & gtk4.

https://github.com/dropbox/nautilus-dropbox/blob/master/ChangeLog

Version 2022.12.05
------------------
* Update to use libnautilus-extension-4 and gtk4, supporting Nautilus 43+.
* Fix various uses of deprecated APIs, such as the "DeprecationWarning: isSet()
is deprecated" warning.
* Fix colors of ignored files in `dropbox filestatus`.
* Remove the long-broken `dropbox puburl` command.
* Don't print a ticker to stderr if it's not a tty.

Version 2020.03.04
------------------
* Coerce XDG_CURRENT_DESKTOP to "Unity". This works around the dropbox binary
that will only activate the indicator icon and menu on Ubuntu Unity < 16.10.
This patch coerces XDG_CURRENT_DESKTOP to report as "Unity" for the budgie-
desktop
