'RegisterToolWindowTask' is marked unstable with @ApiStatus.Internal

Hi,

I am trying to register a toolWindow programmatically using the below code. However, when I use RegisterToolWindowTask programmatically, I get a warning saying that it is marked illegal. I just wanted to know whether the below way is correct way to do it or not. I also want to change contents of this toolWindow later from different classes.

toolWindowManager = ToolWindowManager.getInstance(project!!)

val task =        RegisterToolWindowTask(taskName,
                                         ToolWindowAnchor.BOTTOM,
                                         findingsWindowPanel,
                                         sideTool = true,
                                         canCloseContent = true,
                                         canWorkInDumbMode = true,
                                         shouldBeAvailable = false)

toolWindowManager!!.registerToolWindow(task)
