How can you use Credential Vault content in python extensions

[r_weber]

It seems impossible to pass credential vault content (e.g. user/password values) to a python extension so that it can be used in code.

I came across this post which describes how to add credential vault UI configuration, however this doesn't pass the actual content to the python extension, only the VAULT-ID is passed.

Does anyone know how I can e.g. get the username/password into my custom python extension?

Thanks

hey @r_weber I was just running into this for an api token I'm storing. the post by @Julius_Loman  on this thread
https://community.dynatrace.com/t5/Extensions/Send-a-credential-from-credential-vault-to-extension/m...
did it for me. It all has to do with the activationSchema.json. Here's what he had configured:
it looks to me the key here is to have the credentialVaultId entry and then subsequent values have the property 

useCredentialVault
