Tecno Spark Go 2023 BROM mode

I'm trying to download a custom ROM on my Tecno Spark Go 2023, and I'm trying to unlock the bootloader with MTK Client. I already downloaded the drivers and all, but when I try to connect the phone and reach BROM mode, I can't. I tried many times with different buttons, but I don't get into BROM mode. Any help, please?
