It's too late but I wanted to do it

I don't know if it was a bug or I just didn't get it, but in theory I should have the cape they gave for having Minecraft Java and Bedrock on the same account. Sadly, I don't know if I didn't meet some requirement or they just didn't give it to me. The vanilla cape. I've had Minecraft since 2016, along with bedrock, so it's been a while.
