Add a value to Array in document

I have a collection where one of the attributes is an Array. I want to add a value to this array, and to make it as efficient as possible The simple way would be :

• To get the Array,
• to add the new value to the Array
• to update the document with the new array

but it requires 2 interactions with the database (and if I dont know the ID of the document, 3) I am trying to make it all in a single interaction: Just to add the vew value in the Array with the UpdateDocument function Is it possible?

Thanks,

Array operations like this aren't available yet

you can achieve this with the help of cloud function.

Thank you
