Hi, thank you for trying out the plugin.

When selecting links, a popup will display in the browser requesting for permission to open an external link. It should open after confirming.

If this issue persists, please let me know and I'll do my best to help.

Edit: A bug was reported on the project GitHub page which highlighted an issue regarding a hard coded vault name in the code. This might resolve the issue that you had. Sorry that I wasn't able to notice this sooner!
