Unable to map value in panel display

I am using version 8.3.4

In my dashboard I am getting sensorID as shown in the below screenshot -

Instead of getting A81758FFFE065607 I want to display as Sensor 1.

I tried Value mapping but that didn’t work for me . PFB screenshot

I have configured influxDB to get these sensorIds. and have created a variable which is returning these sensorIds. PFB screenshot

Instead of backend value of sensors (as edited in screenshot as sensor_Id) I want to display as Sensor Id 1, simultaneously same for other sensor ids as well.
How can I map these sensorIds with the custom name that I want to give. Please suggest on this.
