Javascript API - need ability to force chat widget to display inline

I’m attempting to embed the javascript API, replacing Intercom. What’s important to me is the ability to use my own icon/button for support on my site (in the nav) – which would then trigger an inline chat messenger window. I’m halfway there with the Tawk To Javascript API, as I can start the chatbox programatically via window.Tawk_API.toggle(); – but running that always pops up a new window for the chat.
How do I force window.Tawk_API.toggle(); to always open the chatbox inline/overlayed at the bottom right of my site and never as a popup?

I just learned that this can be done through a simple config change by updating the TawkTo Administration → Chat Widget → “On Click Behavior” setting to “Maximize.”
