OPC Ua Connection with Grafana

Hello everyone, I am configuring OPC UA as data source ([OPC UA (Unified Architecture) plugin for Grafana | Grafana Labs] however on the install instruction there is a yarn install and build instruction to build the plugins dependencies. I have tried to run yarn build with corresponding github [ grafana/opcua-datasource: An OPC UA datasource for reading from OPC UA servers (DA/HDA/AE) into Grafana directly (github.com)] nothing working. Can anyone please share the right procedure for connection of opc ua with grafana.

Hope any can show us how it is done.

Thanks in advance.
