I'm new to flashing GSI. I don't know what I need to wipe in TWRP, I need some tutorial for flashing GSI on my device, which is SM-A125F running Android 12.

There are quite a few guides on XDA that address your question. Did you search before posting?

As a courtesy, here is a guide; just substitute whatever GSI you want to flash. The principles remain the same.

Thank you. I just want to make sure my phone won't be bricked. Sorry if I wasted your time.

Remember that "brick" means your phone is completely useless - it's about as useful as a brick, and you can do nothing to fix it. This is generally only the case in seriously extenuating circumstances when you REALLY screw something up, like corrupt the bootloader. I don't think it's possible to do this via TWRP, so it's nothing to worry about. If a GSI fails to boot, you can simply boot back into TWRP and try again.
