Accidentally flashed TWRP on both A/B partitions on Xiaomi Mi A2 Lite

I decided to try to root my Xiaomi Mi A2 Lite. I accidentally flashed twrp-3.2.3-0-daisy.img on both A and B partitions. Because of that, now I can only access the TWRP menu. I think I should download the official ROM and get its boot file, but I'm not sure and I don't want to mess it up more. I've downloaded the ROM and found this boot.img file. . If that's it, is it enough to flash it? And in which partition? A or B?
