is there any possibility for the library to give 'suspicious site alert' on Edge browser

[arafat0007]

[What I am doing]
I display pdf using the library.
Input: Blob data returned from backend
output: using Blob data to display as pdf

Sample code for backend returning data:

//getting data from azure blob storage and returning data
blob_client = azure_blob_storage_service.get_azure_blob_client(azure_blob_service_client, document_name)
dataBytes = blob_client.download_blob().readall()
return send_file(
  io.BytesIO(dataBytes),
  download_name=document_name,
  mimetype='application/pdf')

setting data in Frontend:

const response = await fetch(baseURL+'/chats/'+chatId+'/document', {
  method: 'GET' ,
  headers: {
    'cache-control': 'no-cache',
    }});
    
    // Read the response as an ArrayBuffer
    const data = await response.arrayBuffer();
    
    // Create a blob from the response data
	const blob = new Blob([data], { type: 'application/pdf' }); //it is set to file of <Document />

Other setting:
pdfjs worker setting
pdfjs.GlobalWorkerOptions.workerSrc = '//unpkg.com/pdfjs-dist@${pdfjs.version}/build/pdf.worker.min.js';

[Issue]
After deploying the work, I have seen 'suspicious Site' alert on Edge browser. Chrome is fine.

Can the below be a reason of unsafe alert?

I think that domain URL is not the issue as I have another functionality whose URL is URL/something and I did not get error for that.
