Question: Is there a way to sign out/change accounts on the itch.io release?

[RSpak]

I've been playing the itch.io versions since around December because can't seem to do anything to run the browser versions in a playable manner. At the time, I signed into my "RSpak" Newgrounds account, which I hadn't touched in years. Since then, however, I've created a new Newgrounds account (along with accounts on other platforms) separate from that old one for the sake of creating a fresh online presence for my art's sake, not mixing it with my old usernames/accounts. I'm interested in having my new account reflect my scores, but I don't have any idea on how to change which account the game links to. Is there anything at all in my PC files or Newgrounds account that I can access to sever the connection between the game and my old account?

ALSO: It's occurred to me that this account link feature may not present in the itch.io releases anymore. Is this the case? Or is it still present?

I haven't seen anybody else bring this up, and it isn't a huge deal, but I would love to be able to have my active NG account display my scores rather than my inactive one.

lmk if there is anything I can do about this
