Hi I build a Task component. I would like to add the view all button from the standart into the top right corner. Could you tell me how to modify my code so I can achive this. (I will only show the code sample of the first section "Überfällig" so it will be easier to read)
I already found this side but I dont know how to implement it in my code: https://www.infallibletechie.com/2018/07/adding-view-all-button-in.html

Greetings
