Xolo Era X 4G model has the MicroUSB 2.0 support. And this model is not hardware enabled for the USB on-the-go driver support. And no way to connect the OTG cable to the device. In short Xolo Era X does not support the OTG support.
Unfortunateely, though Xolo Era X 4G has microUSB v2.0 as one of its communication features, it has nott included OTG support in any sense. Neither they have provided the hardware support for it, nor you can avail it through any external device. The driver has not been installed in this model.
There is no OTG support in xolo era x. Even after updating the Operating System, OTG was not supported. During manufacturing this device OTG was not installed. This device already comes with 4G/LTE, but in India 4G-band 40 was not supportable.
