they told me and this was a few years ago that it went to Kasikorn in BKK but u can’t get the paperwork from Bkk to say it was an international transfer. I then opened a Bkk account and it showed as international transfer but sounds like that has changed now
I used Wise to transfer money to Thailand with Kasikorn a few years ago and it didn’t show up as international and they wouldn’t give me paperwork to show international transfer
