Get Paginated Report Parameter names, values or definition that are Embedded in a Web site

Hello all

Currently I am using the latest version of powerbi-client for javascript to embed reports. Now I have embedded a paginated report using the interface IPaginatedReportLoadConfiguration, because with this interface I can set the parameters of my report from my web to the report like the next code:

const config: IPaginatedReportLoadConfiguration = {
            accessToken: token,
            tokenType: models.TokenType.Embed,
            embedUrl: embedUrl,
            type: 'report',
            id: id,
            parameterValues: [ {name: "myname", value: "value" } ],
            settings: {
                commands: {
                    parameterPanel: {
                        enabled: true,
                        expanded: true
                    }
                }
            }
        };
this.powerBIService.embed(element, config);

this is working fine, but I need to know the list of parameters dynamically because my paginated reports can have different amount of parameters. if there's any way to get the list of paginated report parameters ? I haven't found any information in the the sandbox.
