Semantic Mediawiki: Datatable format isn't working

[YousufSSyed]

I have two subobjects in one page:

{{#subobject::
 |Label= Test
 |Text= test
 |Date= Dec 4 2020
}}

{{#subobject::
 |Label= Test
 |Text= test
 |Date= Dec 4 2020
}}

And this query in another

{{#ask:[[Label::+]]

|?Label

|?Text

|format=datatables

}}

I followed the instructions here for installing Semantic Result Formats, which supports datatables, but it can't get show datatables to show up. How can I fix this?
