event grid autentication problem

We have the event grid id3MqttEventGrid

We have the business application MQTTINGESTION

The business application MQTTIGESTION has a client secret

The .NET server calls the HTTP API https://login.microsoftonline.com/{azureTenantId}/oauth2/v2.0/token passing the parameters azureClientId and azureClientSecret

Azure correctly responds to the call returning a JWT token

The problem is that using this JWT token the web application running in the browser cannot connect to the MQTT websocket server. The application connects to wss://xxxeventgridxxxx.westeurope-1.ts.eventgrid.azure.net/mqtt, port 443.

It passes the OAUTH2-JWT packet and as a value uses the JWT returned by the call made by the .NET server
