How to remove a database on DEVONthink To Go

I have deleted a database in DEVONthink on iMac.
This database was synched before to DEVONthink To Go on iPad.
How can I remove now the synched data and the database entry on iPad.
I don’t like to waste the memory space on iPad with a lot of data not used any more.
Thanks for your answer

From the main screen, just swipe to delete the database.
