Modifier of-type is not supported for search parameter 'identifier'

When trying to perform a search for a coverage resource and using the search query:

` Coverage?identifier:of-type=http://terminology.hl7.org/CodeSystem/v2-0203|SN|123456 `

We are getting back a ` 403 Forbidden ` error containing the issue:
```
"issue": [
{
"severity": "error",
"code": "invalid",
"diagnostics": "Modifier 'of-type' is not supported for search parameter 'identifier'."
}
]
```

I did see that support was added according to this PR:
https://github.com/microsoft/fhir-server/pull/2149

Can anyone provide guidance on if this supported and/or guidance on how to get this Modifier to work.

I appreciate any help regarding this question.

Start by reviewing PR #2149 and reproducing the Coverage search query shown in the issue. Determine whether that change covers the identifier:of-type modifier, then verify the expected response and document the required behavior or guidance.
