SimpleJSON data source not found even if is installed

I Installed grafana-enterprise-8.3.3.linux-armv7.tar.gz on raspberry pi : Linux rpi 5.10.63-v7+ #1457 SMP Tue Sep 28 11:25:31 BST 2021 armv7l GNU/Linux
Then I installed grafana-pandas-datasource 0.1.2 python module in order to use grafana with python, and finally I follow the steps described here in order to install the plugin and finally I restarted the application, but when I search for SimpleJSON data source, there is no available on the list.
What Im doing wrong ?

You could try installing the plugin using the Plugin catalog | Grafana Labs.

For now no, I did not know that option. All I can say for now is that installing the binary from tar file and then following the instructions doesn’t find installed plugin, but if I install the debian package it does. I think that in the first case even if installs the plugin in the /var/lib/grafana/plugins directory it looks elsewhere. So, may be a path problem.
