JSON:API How to retrieve multiple values in a CONTAINS condition?

I’m using JSON:API module (in core since v8.7), and works well for a simple query like:

Retrieve all articles with title that contains “MyKeyValue” or subtitle that contains “MyKeyValue”

That, translated in jsonapi query, is:

fields[node--article]=title,field_subtitle filter[or-group][group][conjunction]=OR filter[status][value]=1 filter[title-filter][condition][path]=title filter[title-filter][condition][operator]=CONTAINS filter[title-filter][condition][value]=MyKeyValue filter[title-filter][condition][memberOf]=or-group filter[subtitle-filter][condition][path]=field_subtitle filter[subtitle-filter][condition][operator]=CONTAINS filter[subtitle-filter][condition][value]=MyKeyValue filter[subtitle-filter][condition][memberOf]=or-group 

But HOW to manage multivalues within the CONTAINS condition? I mean: how to accomplish a query like:

Retrieve all articles with title that contains (“MyKeyValue” AND “AnotherKeyValue”) or subtitle that contains (“MyKeyValue” AND “AnotherKeyValue”)

I tried to pass multiple values in this way:

... filter[title-filter][condition][operator]=CONTAINS filter[title-filter][condition][value][]=MyKeyValue filter[title-filter][condition][value][]=AnotherKeyValue ... filter[subtitle-filter][condition][operator]=CONTAINS filter[subtitle-filter][condition][value][]=MyKeyValue filter[subtitle-filter][condition][value][]=AnotherKeyValue ... 

But does not work.
