Shopify Product api create seo meta tags like noindex,notranslate and nosnippet

[apoorv_dev]

Hi I am using the Shopify admin rest api in an embedded app and I need to update the Product meta filed with nosnippet and notranslate
the appropriate meta tags would be 

<meta name="robots" content="max-snippet:0">

and

<meta name="robots" content="notranslate">

I can add the noindex and nofollow using the namespace SEO and the key hidden https://shopify.dev/api/examples/marketing-seo#hide-a-resource-from-search-engines-and-sitemaps

and I can see the appropriate meta tags on the product page.

SEO namespace supports hidden key can I get a list of options supported by the SEO and the other namespaces.
How do I add the other SEO-related meta tags on the product page and if I add some custom meta tags How do I show it on the product page in the front end?
