Can I find/see the requirement I linked inside a test sequence that is inside a test harness in Simulink with Matlab script?

I tried using the line of code below...

sltest.testsequence.readStep([model,'/Test Sequence'],steps{g})

...hoping to catch the linked requirement inside the Test Sequence step. However I only get the struct with the fields:

               Name: 
             Action: 
         IsWhenStep: 
      IsWhenSubStep: 
        Description: 
    TransitionCount:

Is there a way I could try to see the requirement just through Matlab Script?

Even I'm trying for the same. Please post line of code how to catch the linked requirement inside the Test Sequence step if you have got resolved.

Here's how you can do this via existing APIs (using our do178CaseStudyStart demo)

%Block path to test sequence diagram

myTS = 'AHRS_Voter_Harness_HLR_12/Test Sequence';

%extract steps

myTS_steps = sltest.testsequence.findStep("AHRS_Voter_Harness_HLR_12/Test Sequence");

%Get the Stateflow object for the Test Sequence block

tsObj = root.find("-isa", "Stateflow.ReactiveTestingTableChart", "Path", "AHRS_Voter_Harness_HLR_12/Test Sequence");

%Loop through all steps to extract requirement information

for ii=1:length(myTS_steps)

state_step = tsObj.find('-isa', 'Stateflow.State', 'Name', myTS_steps{ii}); %Stateflow object for the step "chart"

outlinks = slreq.outLinks(state_step); %Get outlinks for the step "chart"

dest = arrayfun(@(x) x.destination, outlinks{ii,1}); %Get the destination information

%Example of packaging the data

reqInfo.(myTS_steps{ii}).path = state_step.Path;

reqInfo.(myTS_steps{ii}).stepContent = state_step.LabelString;

reqInfo.(myTS_steps{ii}).reqLinks = dest{ii,1};

end
