These are the limitations to the Custom Screen Actions that you can add: Screen action length can be up to 256 bytes long. 50 screen actions per screen.
Dynamic Elements: If your element changes it’s content dynamically, make sure to call the method for each change of the content if you’d like the elements to be separated.
Otherwise, the elements will be merged despite their changed content. E.g. a ‘Next’ button that changes it’s text to ‘Done’ on the last step of an onboarding flow.
