Edit create modal actions

How to remove "create && create another" and edit label of a "cancel" button. I searched a lot but I cant find this information. Thanks for helping!

Solution

In the action put

->createAnother(false)
->modalCancelActionLabel('put what you want')

->createAnother(false)
->modalCancelActionLabel('put what you want')

->createAnother(false)
->modalCancelActionLabel('put what you want')

->createAnother(false)
->modalCancelActionLabel('put what you want')
