Help needed re extensions ⚡️

I have nostr:npub1tnpfz60snm7ler8k8c69335n37we6690qttl88t556yzkjxhahjq3kkkpe and nostr:npub12vkcxr0luzwp8e673v29eqjhrr7p9vqq8asav85swaepclllj09sylpugg apps installed and can’t figure out how to sign in to Primal with Nostore extension?

Is this only possible on Safari, and not in the Primal app?

Clearly I don’t understand how extensions work 😅
