Now we have to add sheet and get action filter and if we use any object from dashboard it could be a static. new version added with click event and we will wait for new version and updates.
You can't currently add an action to the text/image. However, there are a couple of ways around this. The first option is to create a worksheet that with the text you want, and add that to the dashboard, making it act as a "button." Another option, would be to upload an image in the Button object that has the text you want to use built in.
If you haven't already, I would definitely recommend checking to see if the idea exists in the Ideas section to vote up, and if not, create the idea yourself!
Happy new year!
