Google Slides Classroom Deeplinks

I am a first grade teacher and I am setting up a Bitmoji Google Slides Virtual Classroom to help my first graders learn remotely. I am trying to set up deeplinks so that they can open ups with the click of a button. They will all be using ipads. I have icons for different educational programs in our Google Slides Virtual Classroom. I would like them to be able to click on the icon and have it force open the app on their iPad. The apps I am trying to link to are Zoom, Doodle Maths, Kids A-Z, Seesaw, Flipgrid, and Google Classroom.
