How to filter by description of document in Telegram

Question

I have this code:

def initiate_sticker_set(update, context):
    context.bot.send_message(update.message.chat.id, "initiate sticker set")

initiate_sticker_set_handler = MessageHandler(Filters.text("hello"), initiate_sticker_set)
dispatcher.add_handler(initiate_sticker_set_handler)

I want this Filter to catch not only plain text messages, but also documents with description "hello". How to do it?

In order to capture for example png document with description "your_descpription" or "your_descpription2", use MessageHandler the following way:

initiate_sticker_set_handler = MessageHandler(Filters.caption(["your_descpription", "your_descpription2"]) & Filters.document.mime_type("image/png"), initiate_sticker_set)
dispatcher.add_handler(initiate_sticker_set_handler)
