Some updates on the Issue
I found references for all the files inside src/plugins/home/public/application/components/tutorial

Now some of these files are interrelated , I assume we can't delete tutorial.js as it's being referenced in here:

OpenSearch-Dashboards/src/plugins/home/public/application/components/home_app.js

Line 37 in d8cbc17

import { Tutorial } from './tutorial/tutorial';

Here's the problem

number_parameter has been referenced in parameter_form:

OpenSearch-Dashboards/src/plugins/home/public/application/components/tutorial/parameter_form.js

Lines 33 to 34 in d8cbc17

	import { NumberParameter } from './number_parameter';
	import { StringParameter } from './string_parameter';

Then parameter_form is referenced in instruction_set but used only once:

OpenSearch-Dashboards/src/plugins/home/public/application/components/tutorial/instruction_set.js

Line 34 in d8cbc17

import { ParameterForm } from './parameter_form';

Here's the usage :

OpenSearch-Dashboards/src/plugins/home/public/application/components/tutorial/instruction_set.js

Lines 261 to 271 in d8cbc17

	render() {
	let paramsForm;
	if (this.props.params && this.state.isParamFormVisible) {
	paramsForm = (
	<ParameterForm
	params={this.props.params}
	paramValues={this.props.paramValues}
	setParameter={this.props.setParameter}
	/>
	);
	}

Then finally we have instruction_set referenced in tutorial which we can't delete due to it's reference mentioned at the begining:

OpenSearch-Dashboards/src/plugins/home/public/application/components/tutorial/tutorial.js

Line 36 in d8cbc17

import { InstructionSet } from './instruction_set';

My Understanding

So basically I can remove parameter_form reference from instruction_set and delete it since it's used once & then I can also delete number_parameter & string_parameter since they are not referenced anywhere else, hopefully that won't give any errors
@joshuarrrr Can you confirm if I can delete these or not?
