help: Can't migrate code from version 2 to 3

[TWpgo]

I have the following code snippet which works great with version 2 but I don't get it working properly with version 3.
Maybe someone could help me:

const appInsights = require("applicationinsights");
const { CorrelationContextManager } = require("applicationinsights/out/AutoCollection/CorrelationContextManager");
const Traceparent = require("applicationinsights/out/Library/Traceparent");
const util = require('applicationinsights/out/Library/Util');

async function main() {
    process.env["TRACEPARENT_HEADER"] = `${Traceparent.DEFAULT_VERSION}-${appInsights.getCorrelationContext().operation.id}-${appInsights.getCorrelationContext().operation.parentId}-${Traceparent.DEFAULT_TRACE_FLAG}`;

    ...
	
    const availabilityTelemetry = {
        id: crypto.randomUUID(),
        ...
        tagOverrides: {
            'ai.cloud.role': 'MyCloudRoleName',
            'ai.cloud.roleInstance': myDynamicCloudRoleInstanceVar,
            'ai.application.ver': versionDerivedDuringMainExecution
        },
        properties: {
            ...
        }
    };
    appInsights.defaultClient.trackAvailability(availabilityTelemetry);

}

appInsights.setup(process.env["CONNECTION_STRING"]).start();
const context = CorrelationContextManager.generateContextObject(
    util.w3cTraceId(),
    util.w3cSpanId(),
    'TestCafe'
);

appInsights.wrapWithCorrelationContext(main, context)().then(failedCount => {
    process.exit(failedCount);
});

I struggle especially setting the cloudRoleName or ai.application.ver values in version 3.
Also I don't understand the context handeling in version 3. In version 2 it's pretty simple.
But in version 3 I can't modify it.

Regarding cloudRoleName, it can be configured using the OTEL_RESOURCE_ATTRIBUTES environment variable in 3.x: #1365.

Regarding support for correlation context, please refer to: Application Insights v3.x Unsupported Properties. If you need thiskind of control over the correlation context we suggest staying on 2.x SDK until it's possible to migrate to the Node.js OpenTelemetry distro.
