Collabora Online (code) charts?

Hello, I would love to replace my need for word online/ google docs with nextcloud and collabora (which i have already setup and working), but due to my college need i have to minimally be able to add and edit charts. I cannot for the life of me find how to do that and moreover, when i manually added a chart (with local libreoffice) and tried to edit it (via doubleclicking) the chart just dissappeared…

Also, are formulas in code yet?

PS: some tech info
apache2, nextcloud 11.0.3 on ubuntu 16.04 (without docker)

collabora latest code (with docker from collabora/code)
