How can a beginner use doc_node_id to verify token positions in original text?

Hi! I'm new to using SkillNER and I have a question about the doc_node_id field.

When I extract skills, I get results like this:

{
    'full_matches': [
        {
            'skill_id': 'KS122Z36QK3N5097B5JH',
            'doc_node_value': 'web development',
            'doc_node_id': [435, 436]
        }
    ]
}

I understand that doc_node_id represents the position of the skill in the original text, but I'm not sure how to use these numbers to verify the actual words in my original text.

I tried something like:

original_text = "... my job posting text ..."
original_text[435]  # Doesn't work because this gives a character, not a word
