Change user or delete user

Hi,

I would like to change my username before starting to be an active part (this is my first post ever)
But I didn't find how to do it.

So I wanted to delete my profile in order to reconnect under a new name (connected over Google-Account). But I didn't find how to.

Trying some internet search engine only provide answers about user management under neo4j community edition :frowning:

Need help. thx.
