    Something like this:

    public async Task<List<ChatThread>> GetThreadByIDS(List<long> ids)
{
     var result = await this.dbContext.ChatThread.Where(x => ids.Contains(x.Id)).ToListAsync();

     return result;
}

    Assuming that you have a list named "listOfIds" and your entity is "students".
    so your query should be :
    dbContext.Set().Where(x => listOfIds.Contains(x.Id));
