Hey, I could use some advice... I have a bunch of screen designs for a web app from our designers in Sketch that I can export as PNG. I need a tool that will allow me to construct a clickable interactive demo... Such that I can identify a clickable region on one screen that will lead to another. Etc. I need it to be easy and intuitive... I don't have a lot of time to invest. The demo consists of maybe 10-15 different screens. It's not complex. Ideally it's viewable/usable in a browser when I'm done so I can share it with stakeholders by sending them a link. A nice to have is that if a screen design changes slightly it's easy to update the demo without too much rework. Thanks for any suggestions!
