Hi,

curl --location 'https://api.powerbi.com/v1.0/myorg/groups/xxxxxxx-xxxx/reports/xxxxx-xxxxx/ExportTo' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer XXXXXXXXXXXX' \
--data '{
"format": "PDF",
"powerBIReportConfiguration": {
"identities": [{
"username": "XXXXXXXXXXX",
"roles": ["XXXXXXXXXXXXX"],
