Toast remain open indefinitely until the user closes it

[codeBelt]

Describe the feature / bug 📝:

I couldn't find it in the documentation, but is there a way to keep the toast visible indefinitely until the user decides to close it? Perhaps setting the duration to null or introducing a sticky property could provide this functionality to developers.

We have this toast that we want the user to click on and not have it go away:

Looks like Emil went with duration: Infinity to prevent auto closing.

Like @binkydog mentioned. duration: Infinity is the way to go here.

Infinity is a bit unfortunate, as JSON does not include it and we triggering/controlling some toasts from certain server responses 😅
