Let users know that panel can be collapsed and extended

Is your suggestion related to an experience ? Please describe.
Though there is a change in side panel, the hamburger action button seems to have no state change. I personally feel, it can be dynamic, showing extended vs collapsed view as two different states (icons that switch one to other).

Describe the improvement
We can use the regular hamburger for one of the states where the current one can point to the another state.

How is this icon intuitive enough to say that it is collapsible? 🤔

[pavinduLakshan]

We need to keep the application panel open/closed state and show different icons based on that.
