A possible solution would be for Opera to add WhatsApp Business as a sidebar app, which would enable users to have two WhatsApp accounts open at the same time. This would provide greater convenience for those who need to manage both their personal and business WhatsApp accounts simultaneously.

That will work, cz i have tried.

I hope, this will work.

It's possible that there's an issue with your keyboard or a bug in the WhatsApp application that's causing it to restart or the text box to disappear when you use the shortcut keys. Try checking your keyboard settings or updating/reinstalling WhatsApp to see, if that resolves the issue.
