Feature request: Option for alt text for plotly plot in shiny app

I was recently trying to add alt text for a plotly-based animated plot within a shiny app. I saw that there is a comparatively recent option to add alt text via an alt argument in, e.g., package shiny's renderPlot(). I didn't see anything similar in R plotly. Is it possible something similar could be extended for renderPlotly()?

I was able to get alt text added to my plot via htmltools::tagAppendAttributes() in the UI code, although it took me a bit to get it (apparently) right.

Inizia tracciando il punto di ingresso renderPlotly() e confronta il comportamento dell’argomento alt descritto per renderPlot() di shiny. L’attuale workaround con htmltools::tagAppendAttributes() mostra il risultato desiderato; il lavoro sarà completato quando esisterà un modo equivalente per fornire testo alternativo ai grafici plotly in un’app shiny.
