I suggest to learn how to get debugging up and running using for instance visual studio code:

Hey,

yes, I have tried the way that was suggested in the link which you send. Now, I need to know how to see the output for this. By following the link I have used Logic analyzer but I can't able to get any output. Kindly help me to get it done

Have you verified that the example work as-is?
https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/peripheral/lpuart/README.html#requirements

Then it should be fairly simple to measure on UART pins, for pin-out see printing on the back of nRF5340DK or the dts file:
https://github.com/nrfconnect/sdk-zephyr/blob/main/boards/arm/nrf5340dk_nrf5340/nrf5340_cpuapp_common.dts#L142

You can attach a large pull-up resistor to the RXD pin if it's not connected to anything, the CTS pin should be low to receive data on RXD when hardware flow control is enabled.

Hi,

Sorry for the delay, Now I am facing some issues because of nrf connect to update. Afterwards, I will contact you

Can you try to example project stand-alone first, with the pins shorted as described:
https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/peripheral/lpuart/README.html#requirements

Also try with a pull-up (e.g. >10kohm) on the RX pin if possible to see if that make a difference.
