WhatsApp Chat Recovery from Mobile device

I'm in need of a professional to help recover deleted WhatsApp chats from my iPhone. The chats I need to recover are specific conversations, not all chats.

My phone is regularly backed up on iCloud, and WhatsApp is synced on my laptop. I haven't attempted any recovery methods yet, so you're free to explore all possible options, including:
- iCloud
- Local backups
- Forensic tools
- Third-party software

Thanks
