Issue: SharePoint SSO Component

[krriscode]

Hi Ms Team,

I have used this code same for Copilot SSO https://github.com/microsoft/CopilotStudioSamples/blob/master/BuildYourOwnCanvasSamples/3.single-sign-on/index.html
The SSO is working fine as expected, it's not asking to login for already sign-in user on SharePoint

But I'm facing issue with SharePointSSOComponent in
https://github.com/microsoft/CopilotStudioSamples/tree/master/SharePointSSOComponent/src/extensions/pvaSso
second post activites https://directline.botframework.com/v3/directline/conversations/'$id'-us/activities

payload :
{
"type": "invoke",
"name": "signin/tokenExchange",
"value": {
"id": "efd68c13........",
"connectionName": "913848c13........",
"token": "ebyt-secrete.............................................................."
},
"from": {
"id": "my-userid@mail.com",
"name": "my-user-name",
"role": "user"
}
}
response error : {
"error": {
"code": "BotError",
"message": "Failed to send activity: bot returned an error"
},
"httpStatusCode": 412
}
