Just be sure to save your keys to a backup.
Writing down your owner key is a good idea.
Other than that the process is pretty straight forward.
Do you have an element account?
This is my room, it is public.
Dm's are private.
If you make one, I can walk you through it.

I'm not sure what an element account is, but I will read the link you provided.
Element.io is a web2 chat/dm platform, it's advantage is that it is open source and dm's are encrypted.
You are right to be careful changing keys, but it is pretty straight forward, there should be an option to download all the keys to a data file, writing down the owner key is a good idea in case the electronic copy dies.
Are you describing the chat room I have accessed from the top of my PEAKD dashboard that is right between the pencil symbol and the bell symbol?
No, that is sting.
We can do it there, too.
It's encrypted.
I actually did click into https://app.element.io/?updated=1.11.59#/room/#hivediscord:matrix.org. One concern that I did have was that it indicated to me that I needed to upgrade my browser. I'm not crazy about that. So what I will do is try to work with the browser I have in going back into that website you pointed out to me and exploring.
