If you donated a minimum of 5 Euro you will get an email with a JWT token to get access to the Plus data for one year. If you use the TV-Browser plugin you can enter this token in the plugin's settings dialog. If you are using Xmltv instead, make sure the system you use is able to add the token to the header of each request (see Access the data). Otherwise access to the Plus data will not be possible.
