Matrix Tile custom columns help

I’m trying to recreate a SCOM dashboard in SquaredUp for TLS Compliance.
This is the SCOM version:

The column headers are the properties from SCOM listed here:

This is the dashboard JSON. The bit for dotnet works.

{
	"title": ".Net Framework Version",
	"_type": "celltile/text",
	"config": {
		"display": {
			"contentTemplate": "{{properties.dotnet}}"
		}
	}
},

This bit to try and populate the SsL_2.0cl column doesn’t:

{
	"title": "SSL2.0 Client Status",
	"_type": "celltile/text",
	"config": {
		"display": {
			"contentTemplate": "{{properties.ssL_2.0cl}}"
		}
	}
},

I’m taking a punt that it’s to do with the underscore or fullstop characters in the ssL_2.0cl property - how do I escape those in JavaScript?

Answering my own question “{{properties.ssL_2\.0cl}}”
