Retriving Personal access token once used to activate a Word press theme

Hello All,

I bought a word press theme in 2018, which i activated then and used. I have since pull down the blog and now i need the theme for a new blog, but am unable to get the access token back so i can activate the theme. I generated a new personal access token but the activation process fails.

How can i retrieve the initial access token i used to activate theme? Thanks.
