How to add custom meta description for collections/all

I need to update a custom metadescription for collections/all URL.

I tried to give using if condition by fecthing the canonical_url.But it didn’t worked.Also tried to do by checking the template name.But that also didn’t work.

Why does shopify doesn’t allow to update the meta description of collections/all page??
