Sample of a pro bot

Good morning, it's me again.
I wanted to ask if you could create a sample of pro bot on all the channels so that we could try it.

Moreover, I wanted to ask a confirmation about this:
I remember being told that on Telegram the qr could be sent without "Choose:" only if there was no persistent menu, so, if my bot was pro, and since I could remove completely the persistent menu (also Snatchbot branding), then on a pro bot qr could be sent without "Choose:"? Is that right?
