Saves a table of rows as a shareable GSC Wizard report. Pass the rows you got from another tool (e.g. query_top_queries, get_content_group_performance) plus the columns describing which fields to show; the report renders at view time, so the stored payload stays small. THIS IS STEP 1 OF 3: the returned URL opens for NOBODY until access is granted, not even for the account owner, because the viewer is the client portal and requires a client login. To actually share it: (2) create_report_client with the recipient's email, then (3) manage_report_access to grant them the report. Do not hand the URL to anyone before step 3; it will not open. Up to 50 reports per account; delete old ones with delete_shared_report.
