Hello I have a bussines requirement to get some data from chats that are in here: [Eikon Messenger Platform](https://collab.platform.refinitiv.com/eikonmessenger).
So I want to create an application that will be able to get messages exchanged in provided chatroom to extract some data from these.
I was looking at your tutorial that is on github: [MessegerChatBot JavaScritp Example](https://github.com/LSEG-API-Samples/Tutorial.MessengerChatBot.JavaScript).
But what do I have to do to get access to this api: [Messeger API](https://api.refinitiv.com/messenger/beta1)
I am using mine username and password to acquire token and it succeed but when I am trying to use API I get 401:
```
{"error": { "message": "user is not authorized to use the API", "code": 401 }}
```
So I am unable to use this API through this javascript code and from API playground also.
The question is also: am I able to get chat messages history? Because this is requirement also.
If not could you please advice me how can I achieve that?
I am Window user, writing in JavaScript and C# also. I am using code from example I've linked with changed configuration settings to use my credentials.
