Understanding Azure Bot - why can't I get attached file data - azure

Question

I am new to using azure bot service
I have a bot that is used inside Microsoft Teams
I use this bot to send and receive messages inside Microsoft teams
When the user tags the bot and sends a text message I get it in the activity response
But when the user tags the bot and sends an image attached to the message I do not get any information about that image
"attachments" : [ {
"contentType" : "text/html",
"content" : "<div><div><span itemscope=\"\" itemtype=\"http://schema.skype.com/Mention\" itemid=\"0\">BotName12</span> Msg </div>\n</div>"
} ],
above is what I get ,
I expect to get also "contentUrl","content" and "thumbnailUrl"
Is it related to permissions ? If so, where do I define it,
On the Bot, or on the Application related to it?
Thanks

I tried to reproduce the procedure and the image is being uploaded perfectly and the text message also sent successfully in MS Teams.
Follow the instructions mentioned below screen.
Click on Channels to choose MS Teams
Select Microsoft Teams and attach the created bot to Teams Channel. After channel attachment, click on open in teams
The above procedure may not be the code part, but the procedure to create the bot and attach to teams perfectly.
The required contentType and other attachments information can be retrieved by setting name property and contentUrl property to the URL related to the media file. content, contentType, contentUrl, name, thumbnailUrl are the properties need to be given. Then the Activity object which is responsible for your message will specify the Attachment object within your attachments array.
For example, consider the following code for the single image upload.
POST https://your-website/apis/v3/conversations/abcd1234/activities/5d5cdc723
Authorization: Bearer ACCESS_TOKEN
Content-Type: application/json
Here comes, the JSON response for the content uploaded as an attachment
{
"type": "message",
"from": {
"id": "234567",
"name": "sender's name"
},
"conversation": {
"id": "user234",
"name": "conversation's name"
},
"recipient": {
"id": "bot234",
"name": "recipient's name"
},
"text": "Here's a picture of the duck I was telling you about.",
"attachments": [
{
"contentType": "image/jpg",
"contentUrl": "image URL"
}
],
"replyToId": "234"
}
To implement different types of media cards if needed refer. We can include AudioCards as well.
