The bank that opened the letter of credit should send the original letter of credit to the bank designated by the seller, right? (International trade)

The original letter of credit is the old calendar. At present, all letters of credit are opened by electricity, that is, they are sent directly to the advising bank by means of inter-bank telecommunications, and the advising bank receives and prints the original letter of credit, but the advising bank needs to affix a notice seal.
