ICC5 TPMS code

Put new larger heavier tires on my 2022 Cascadia. Manual says I can change TPMS parameters on ICC5 Infotainment system. When I open to TPMS to adjust it wants me to enter a four digit code. Where can I get this code? 3 FL service centers I have called no nothing about it. Dealer knows nothing. Is there a number at FL I can talk to? Sucks driving a truck where TPMS is at warning level all the time.
