How can I include Test ToolKit when creating a Business Central Azure Container?

I have created a Business Central conatiner in Azure using

az container create `
--resource-group 'RG-Container' `
--name 'democontainer’ `
--image mcr.microsoft.com/businesscentral/sandbox:13.1.25940.26323 `
--dns-name-label $'democontainer’ `
--port 80

I want to include testtool kit and the AL languages 

Can i simply add a environment variable , if so which is it , because i cant seem to find it in online docs ?

Thankyou
