Not sure what aftermarket RKE system you are using or the exact model of Corolla but... Don't have the info on a 2021 but here is the basic info on a 2020 Corolla, regular "H" key sedan. 2020 and 2021 are probably the same.
OEM Alarm Arm        GREEN(-) DASH FUSE BOX,BLK 21 PIN , PIN 18
OEM Alarm Disarm      PURPLE(-)DASH FUSE BOX ,BLK 21 PIN , PIN 17
Trunk Release        PINK (REVERSE)          DASH FUSE BOX , WHITE 36 PIN , PIN 20
Parking Lamp (+)      BLUE     DASH FUSE BOX, WHITE 36 PIN , PIN 30
Parking Lamp (-)      GREEN    HEADLIGHT SWITCH , WHITE 40 PIN ,PIN 3
Constant 12 volts     DASH FUSE BOX           WHITE 1 PIN CONNECTOR   
Ignition #1           BLACK    IGNITION SWITCH ,WHITE 8 PIN , PIN 8
Accessory #1          RED(+)   IGNITION SWITCH , WHITE 8 PIN , PIN 6
Use the Arm and Disarm wires to do both lock & arm, unlock & disarm. You will need a relay to do the trunk release as it is a 5-Wire reverse situation.
Soldering is fun!
