How do I search for a specific string inside a mongodb field that contains JSON? (lemmy.world)

I get this is a long shot but hey, lets make some content.

I am trying to search (via mongodb commands) inside fields that contain the following example JSON content:

Each 'Details' field uses the same structure inside the collection:

[
    {
        "references": [
            "https://www.owasp.org/index.php/SQL_Injection",
            "https://cwe.mitre.org/data/definitions/89.html"
        ],
        "locale": "en",
        "title": "SQL injection is possible",
        "vulnType": "Web Application",
        "description": "<p>SQL injection (or SQLi)....</p>",
        "observation": "<p>The following endpoint and subsequent data extraction was found to be vulnerable to SQL injection:</p><p></p>",
        "remediation": "<p>The most effective way to prevent SQL....</p></li></ul>",
        "customFields": [
            {
                "customField": "631816bfcef08a001188c9d5",
                "text": "A03:2021-Injection"
            },
            {
                "customField": "631855d0cef08a001188ca0c",
                "text": ""
            },
            {
                "customField": "63198741cef08a001188ca38",
                "text": ""
            },
            {
                "customField": "638d3ff17406ad001120d10d",
                "text": "C3: Secure Database Access"
            },
            {
                "customField": "639680ce7406ad001120d196",
                "text": "Implementation"
            }
        ]
    }
]

I have tried assorted commands such as:

db.vulnerabilities.find({Details: {$regex: 'Web Application'}}
db.vulnerabilities.find({ Details: { $in: ["vulnType"]}})
db.vulnerabilities.find({ "details" : /vulnType/ }

These are shots in the dark clearly but I cant see an obvious way to look for specific strings or even json pairs. Any help would be appreciated.

So in case another visitor passes by, some nice individual on stackoverflow solved it for:

"Is the single entry array that you've provided representative of a single Details field in the documents? Are you looking for the query .find({ 'Details.vulnType': /Web Application/ })? – user20042973"

Fairly simple query, I just wasnt aware (as a noob) of mongo's ability to read the JSON contents and reference it directly.
