We are trying to use copy to clipboard functionality in HF Spaces, following is the code:
import streamlit as st
from bokeh.models.widgets import Button
from bokeh.models import CustomJS
from streamlit_bokeh_events import streamlit_bokeh_events
from datetime import datetime


current_time = datetime.now().strftime("%H:%M:%S")
text = f"## Current time: {current_time}"
st.write(text)
copy_button = Button(label="Copy Text")
copy_button.js_on_event("button_click", CustomJS(args=dict(text=text), code="""
    navigator.clipboard.writeText(text);
    """))

no_event = streamlit_bokeh_events(
    copy_button,
    events="GET_TEXT",
    key="get_text",
    refresh_on_update=True,
    override_height=75,
    debounce_time=0)

It works well locally, but it doesn’t work on Spaces. It seems copy to clipboard is blocked in an iframe (errror message in the browser console: “Uncaught (in promise) DOMException: The Clipboard API has been blocked because of a permissions policy applied to the current document. See Deprecating Permissions in Cross-Origin Iframes - The Chromium Projects for more details.”), it needs to add specific allowance in iframe, which I don’t know how to do it. Maybe someone has a solution?
