My MS Team Template not Working

Hi Everyone.
I have configured the ms team channel in my bot and tried out a sample ms team template but it is never shown in MS team.

BOT TEMPLATE:
{
“type”: “AdaptiveCard”,
“$schema”: “http://adaptivecards.io/schemas/adaptive-card.json”,
“version”: “1.2”,
“body”: [
{
“type”: “Container”,
“items”: [
{
“type”: “FactSet”,
“facts”: [
{
“title”: “Type”,
“value”: “Paid Time Off”
},
{
“title”: “Balance”,
“value”: “80 hrs(10.0 Days)”
}
]
}
]
},
{
“type”: “ActionSet”,
“actions”: [
{
“type”: “Action.Submit”,
“title”: “Apply”,
“style”: “positive”,
“data”: {
“id”: “_qkQW8dJlUeLVi7ZMEzYVw”,
“action”: “approve”
}
}
]
}
]
}
