Change the name in comment posted in pullrequest via rest api

[aparna_gogst]

Hi ,

We have created a bitbucket app. through which we have created a JWT token using installed app response.

and got the access token for the same using this api 
curl --location --request POST 'https://bitbucket.org/site/oauth2/access_token' \
--header 'Authorization: JWT {JWT token } \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'grant_type=urn:bitbucket:oauth2:jwt'

Now i am using this access token to post a comment on the pull request. The comment is created on the pull request but the posted name is coming as "WORKSPACE NAME for which the app is authenticated. 

Used this api 

curl --location --request POST 'https://api.bitbucket.org/2.0/repositories/ZpcSunSpace/sun/pullrequests/1/comments' \
--header 'Authorization: Bearer {TOKEN}' \
--header 'Accept: application/json' \
--header 'Content-Type: application/json' \
--data-raw '{
"content": {
"raw": "this is summary comment"
}
}'

Here MilkwaySpace is the workspace name for which the app is authenticated. 
I want my app name instead of workspace name here. How can i get it. 

Thanks in advance
