To install Chrome themes in Edge, follow these steps:

1 = Open Edge (Stable, Beta, Dev or Canary) and click on three dots icon to open its menu. Once you’ve opened Edge menu, select “Extensions” In Edge's extension tab, turn on the option “Allow extensions from other stores”

2 - In Edge's address bar, type Edge://flags and enable "Allow installation of external store themes"

3 - head to the Chrome store and install themes.

4 - Any installed theme can be removed by going to Edge settings > Appearance > Custom theme.

good luck
