How to use the @prisma/sdk.dmmfToDml function in @prisma/sdk

try {
      const dmmf = await getDMMF({ datamodel: introspectionSchema })

      // add the datasource itself to the schema in case no schema.prisma exists yet
      const datasources: DataSource[] = [
        {
          name: 'db',
          config: {},
          connectorType,
          url: {
            value: url,
            fromEnvVar: null,
          },
        },
      ]
      const schema = await dmmfToDml({
        config: config || {
          datasources,
          generators: [],
        },
        dmmf: dmmf.datamodel,
      })

      log(`Done with introspection in ${chalk.bold(formatms(Date.now() - before))}`)

      if (args['--print']) {
        console.log(schema)
      } else {
        if (schemaPath && fs.existsSync(schemaPath)) {
          const backupPath = path.join(path.dirname(schemaPath), 'schema.backup.prisma')
          fs.renameSync(schemaPath, backupPath)
