Trying to extract the master jetton address to verify the transaction whether is the correct jetton

[shuucier]

async extractJettonMaster(boc: string): Promise<string | null> {
    try {
      const cell = TonWeb.boc.Cell.fromBoc(Buffer.from(boc, 'base64'))[0];
      const slice = cell.beginParse();

      slice.readUint(32);
      slice.readUint(64);

      const jettonMasterAddress = slice.readAddress();

      return jettonMasterAddress.toString(true, true, true);
    } catch (error) {
      console.error('Error decoding BOC:', error);
      return null;
    }
  }

This will be my code, I seem to have error on cell.beginParse() as it states Property 'beginParse' does not exist on type 'Cell'.ts. My issue is is there another workaround for this kind of extracting method?
