Plotly R: jitter point but without the boxplot

I would like to obtain exactly the same result as the one presented here in the best answer of this post: Add jitter to box plot using markers in plotly, but without the boxplot itself keeping only the jitter points. Is there a way to achieve this? thank you for your answers.

Remove the add_trace. Using the literal code from that answer,

library(plotly)
set.seed(42)
dat <- data.frame(xval = sample(100,1000,replace = TRUE),
                  group = as.factor(sample(c("a","b","c"),1000,replace = TRUE)))

dat %>%
  plot_ly() %>% 
  # add_trace(x = ~as.numeric(group),y = ~xval, color = ~group, type = "box", 
  #           hoverinfo = 'name+y') %>%
  add_markers(x = ~jitter(as.numeric(group)), y = ~xval, color = ~group,
              marker = list(size = 6),
              hoverinfo = "text",
              text = ~paste0("Group: ",group,
                             "<br>xval: ",xval),
              showlegend = FALSE) %>% 
  layout(legend = list(orientation = "h",
                       x =0.5, xanchor = "center",
                       y = 1, yanchor = "bottom"
                       ),
         xaxis = list(title = "Group",
                      showticklabels = FALSE))

We see:
