Added swagger UI on my express app but POST req body is not editable

Hi Below is swagger code for API endpoint for post request. I can see the BODY in swagger UI but when I click on try it now I cannot edit request body.
Below is my code

/*** @swagger* /foods:*   post:*     summary: Creates a food item*     consumes: application/json*     parameters:*       - in: body*         type: object*         properties:*           ITEM_ID:*               type: string*           ITEM_NAME:*               type: string*           ITEM_UNIT:*               type: string*           COMPANY_ID:*               type: string*     responses:*       201:*         description: Created*       400:*         description: Bad Request*       500:*         description: Internal Server Error*/app.post('/foods',[check('ITEM_ID').not().isEmpty().trim(), check('ITEM_NAME').not().isEmpty().trim(), check('ITEM_UNIT').not().isEmpty().trim(), check('COMPANY_ID').not().isEmpty().trim()], async (req,res) => {    let connection;     const errors = validationResult(req);    if(!errors.isEmpty()){        return res.status(400).json({errors: errors.array()});    }    else{        try {            connection = await pool.getConnection();            var itemID = req.body.ITEM_ID;            var itemName = req.body.ITEM_NAME;            var itemUnit = req.body.ITEM_UNIT;            var companyID = req.body.COMPANY_ID;            var sql = `INSERT INTO foods (ITEM_ID, ITEM_NAME, ITEM_UNIT, COMPANY_ID) VALUES ('${itemID}', '${itemName}', '${itemUnit}','${companyID}')`;            var rows = await connection.query(sql);            res.status(201).json(req.body)        }        catch(err){            res.status(400).send(err.message);        } finally{            if(connection){                return connection.release();            }        }    }});

Below is my swagger init code where I set the URL and other settings. Is there way I can make the req body editable. My POST api works fine with postman.

const options = {    swaggerDefinition: {      info: {        title: 'API',        description:'Sample DB CRUD Operations API',        version: '1.0.0',      },      host: '<host>:3000',      basePath:'/'    },    apis: ['./server.js'], // files containing annotations as above  };  const specs = swaggerJsDoc(options);app.use('/docs', swaggerUi.serve, swaggerUi.setup(specs));
