Error when using count - dtplyr 1.0.1

[skiamu]

I'm having the following problem:

library(dtplyr)
library(tidyverse)
dt <- lazy_dt(dplyr::starwars)
count(dt, species)

I get

Error in UseMethod("count") : 
  no applicable method for 'count' applied to an object of class "c('dtplyr_step_first', 'dtplyr_step')"
