A question About queryFilter's function

I need input a user or group type value, and filtering data.

but a question emerged, if field of table is a list of user of group type, "in" of operator is not working.

a!queryFilter(

field:"c1",

operator:"in",

value:ri!user

)

data:

Dictionary

 c1 List of User of Group - 2 item

    user1(User)

    user2(User)

c2 ...

c3 ...

I expected when I input one user, if the user in the list, data is able to filter.
