What is the Matlab code that connects a variable to a Slider Switch Block?

I tried using the code below, but it failed. Please give me a lot of advice.

modelName = 'mdl';
    open_system(modelName);
    modelWorkspace = get_param(modelName, 'ModelWorkspace');
    modelWorkspace.assignin('A', 0);
    scenarioSwitchPath = [modelName '/Scenarios/ScenarioSwitch'];
    set_param(scenarioSwitchPath, "Binding", 'A');

The 'binding' needs to be a block in the model. If that block uses 'A' as a parameter and that parameter is selected to be bound, then it is effectively bound to 'A'.

Make an example model and bind a parameter, make sure it works properly and then get_param(BlockPaht,'binding') to figure out how to set it programingly.

Or check the help document of the Slide Switch block, "Parameters",'Connection", "Programmatic Use" section
