Cryptography result is not correct

This is the problem:
when I encode my text “Hello” with aes-128, aes-256 or tripleDes, I can decode it correctly in the app with decode methodes. But when I use the encoded result in any online tool or in my python app, the encoded result is not correct!
It’s been 8 hours sence I’m looking for my answer. I want to send “Hello” in crypted form to a python app
I konw that kodular uses aes-128 cbc but cbc needs “IV”. But how can I set the “IV”?

example with tripleDes:
key: 0123456789ABCDEF01234567
text: Hello
result from kodular: XdlXMvEkaoQ=
result from uh5ZT+9Oll0=
