Joke Bruggenkamp You didn't specify bunq in your question (only The Netherlands), but I'm gonna assume you want to send money from your bunq account to an Indian bank account that is denoted in Indian rupees (INR).
The bunq app has integrated the services from Wise, so all you have to do is tap on Pay on the Home screen, then choose Select currency and tap on the blue text that says "Currency not here? Use Wise!", which will then open a long list of different currencies to choose from. There you can choose INR and then just go on with your payment.
You will have the choice to send to a bank account (for that you need full name, account number and IFSC) or you can also send to an UPI ID (like name@bankname). The app should show all the needed information and you can just follow the payment flow.
