How to activate a slide-in pane using script (OMI Toolkit)?

Hello Heroes,

I am trying to open a slide in pane containing Historian Client using a script in my ViewApp, not the Hamburger-button.

I have a bit that i set to "True" with a toggle button, then I have a "While True" script running when the bit is true.

I have tried running this;

ArchestrA.Client.ViewApp.ViewApplication.Application.ActivateSlideInPane(MyContent.HistoricalTrendControl1,ArchestrA.Client.ViewApp.SlideInPanePosition.Top);

I get no errors, and nothing in logs when i press the button. But the slide-in pane does not active/slide in. Any help available?

The documentation of the toolkit says to use an reference to a control object and position of slide in pane as parameters in the function call:
