Automate Product Meta-Descriptions in Shopware5

Hey boyes and boyettes,

one of my new clients is using Shopware5 for a big online-shop (over 1.3k products). So far I haven't been able to find a way to automate the meta-descriptions in bulk. While it was easier for meta-titles (via a PlugIn) I refuse to write and implement all of the meta-descriptions for the products by hand.

Since I never worked with Shopware5 before and my 4h of asking Google didn't yield any good results I thought I'd ask in here and see if people found a PlugIn or another solution for this.

If doing this manual is the only solution so be it, but it'd be a humongous amount of time needed.
