How to create projects and attach files to them

I don’t find any way to create a new project.
i expected an icon in the header.
in the Deck app i have an option to add some card or deck to a project, but NO WAY TO CREATE ONE.

my config:
snap nextcloud 18.0.4
Ubuntu 18.04.4 LTS bionic
PHP Version : 7.3.18

yes, it’s a little confusing. It is sufficient to assign the card to an object (map, board, file, …). Then a project with the name of the object is automatically created. with the name og the target, but you can rename the new project

mmmh that is not exciting at all if the “project” concept in nextcloud is just an other tag in the deck application v_v

anybody knows what app could be used to really manage projects in nextcloud ?
