I think the below query is used to print the partner wise partner ledger report. How to modify the query to print a salesperson wise partner ledger report? What extra things should I do?

class ReportPartnerLedger(models.AbstractModel):
    _inherit = 'report.account.report_partnerledger'
    @api.model
    def render_html(self, docids, data=None):
        query_get_data = self.env['account.move.line'].with_context(data['form'].get('used_context', {}))._query_get()
        reconcile_clause = "" if data['form']['reconciled'] else ' AND "account_move_line".reconciled = false
        query =
         """SELECT DISTINCT "account_move_line".partner_id     
         FROM """ + query_get_data[0] + """, account_account AS account, account_move AS am   
         WHERE "account_move_line".partner_id IS NOT NULL   
         AND "account_move_line".account_id = account.id   
         AND am.id = "account_move_line".move_id    
         AND am.state IN %s    
         AND "account_move_line".account_id IN %s    
         AND NOT account.deprecated    
         AND """ + query_get_data[1] + reconcile_clause
