code syntax for sending push to some userIDs

I have an array filled with userIDs. how can I use the query parameter to send a push to all users?

wiki
query can be left empty in which case the notification will be sent to all devices that have registered a token. query can also be one or more ids obtained from clients via Push.id() or one or more userIds associated with the accounts-base package and Meteor.userId().

all users:
query: {}

single user:
query: {userId: "us3r1d5tr1n6"}

what is the syntax to send something like this:

some users:

var myarray : ['sadfsdfddfds2','asdfsdfffsdf3', 'oko34r23ijfsafdf', '123owksfoadkf'];?

query:{userIds: myarray}

is not working

I´m using myarray.forEach() and do a push for each userId but it looks like the wiki says it works also with a list of ids?

Start by checking the wiki's documented query forms and the package behavior for an array of user IDs, then compare that with the reported query: {userIds: myarray} usage and the forEach() workaround. Done means the supported syntax or limitation is confirmed and the wiki or implementation accurately reflects it.
