Getting Board and its associated Sprint details using Oauth 2.0 token is not working.

[Dhilipan]

I have enabled all the scopes for JIRA and generated new token to read Board and sprint related information from JIRA using Rest API method.
But unfortunately I was unable to get records for the api versions like 1.0
/rest/agile/1.0/board/{boardId}
/rest/agile/1.0/board/{boardId}/sprint
For the same toke, api version 3 is working fine.
Sample api which I have used,
/rest/api/3/search?jql="created" >= 2020-09-20

Error message which I have received for api version 1.0 is given below,

{

"errorMessages": [

"OAuth 2.0 is not enabled for this method."

]

}

If Board and Sprint api  support is not provided so far in 3rd version of Rest Api, please let me know. Also let us know, if JIRA is planning to introduce in near future. 

Thanks in advance!!!
