once on the youtube channel and at the bottom of the video description we can see a binary sequence. First reflex, a decoding tool, personally I use asciitohex when I already know the encoding.

00100001 00100001 00100001 00110010 00110011 00110110 00110001 00110001 00110010 00110110 00110010 00110111 01101001 01110100 00110000 01000111 00110001 01011111 01000110 01010100 01000011

the result we get is not directly the flag. it is upside down
