Send email with attachment - MS Graph

Question

good night
I am sending email without user authentication, automatic method, this is working, but I would like to attach several files to the email, how to do this?
I am using the following code to send email.

{"message": {
   "subject": "xxxxxx",
   "body": {
     "contentType": "HTML", "content": "yyyyyyyyyyyyy"},
     "toRecipients": [
       {
         "emailAddress": {
           "address": "ttttt@gmail.com"}
        }
      ]
    }
}

POST https://graph.microsoft.com/v1.0/users/{id}/sendMail
Content-Type application/json
Authorization Bearer " & Token
Host graph.microsoft.com"

I know a parameter called attachment, but I was unable to use it pointing a physical file path, I need to point several files to be sent in the email.
How to make?

The solution would be to add array of attachments(since you want add multiple number of attachments) like -
"attachments": [
{
"@odata.type": "#microsoft.graph.fileAttachment",
"name": "Teste de Anexo",
contentType: 'text/plain',
contentBytes: byteContentOfFile,
},
{
"@odata.type": "#microsoft.graph.fileAttachment",
"name": "File2.txt",
contentType: 'text/plain',
contentBytes: byteContentofFile2,
},
{
"@odata.type": "#microsoft.graph.fileAttachment",
"name": "File3.txt",
contentType: 'text/plain',
contentBytes: byteContentofFile3,
},
]

Hope the solution works for you !!!
