Hide / show slide with button

Hi @harmaddeo,

I’m afraid that something like that is not possible out of the box at the moment but it is something we’re considering adding in future.

At the moment it would require creating a sticky button and then assigning Slide-in to open with that.
You check these examples of sticky buttons:

Within Hustle Slide-in, you would need to go to Behavior tab and select to open on click with your new button ID/class added there and for Closing Behavior option set Keep Showing this message.
