R Shiny DT::renderDataTable ...how to customize title in downloaded table

I am using following code for datatable...

output$table <- DT::renderDataTable({ datatable(data = filtered_data3(), extensions = 'Buttons', options = list(pageLength = 50, dom = 'Bfrtip', buttons = c('copy', 'csv','excel', 'pdf', 'print')), rownames = FALSE) })

when I am downloading the table I'm getting "plotly-logomark" in title. How can I get rid of that and get desired title on the downloaded table. Thanks in advance
