Yvette-Glasius-Turquoise-Starfish Hoi Yvette,
Welcome to the amazing bunq 🌈 Family!
Hmm, I think the best thing you can do is to contact Tellow. I did a quick look for you on their help page but unfortunately couldn't find anything about a direct connection with bunq 😔. They do support a file import, but that wasn't what you are aiming for.
I'm sure Tellow can help you! If there is any thing I can do, let me know
