The Kobo Clara 2024 model doesn't natively support Dropbox integration. We need to install NickelMenu, a third party plugin to enable it.

Follow these steps to enable Dropbox on your Kobo eReader:

• Install NickelMenu: Connect the device via USB cable. Download NickelMenu and extract the files and copy the nickelmenu folder into the .kobo folder. After copying, restart the device.
• Connect the device again, you can see nickelmenu or nm present within .adds folder.
• Open the nickelmenu.cfg file within it and add the following line:

  menu_item:main:Dropbox:nickel_open:library:dropbox

  If you don't find it, create a new file named config.txt and add the above line.
• Save the changes, eject your Kobo.
• Connect the device again. Go to .kobo/Kobo and open the Kobo eReader.conf file.
• Find [FeatureSettings] section, if it doesn’t exist, create it.
  Add the following sections.
  dropbox_link_account_poll=https://authorize.kobo.com/{region}/{language}/LinkDropbox
kobo_dropbox_link_account_enabled=True

Now, Dropbox will be available in the menu. You can link your account and access your files directly from the Kobo eReader.
