Make back arrow exit embedded browser

Today I've visited TechCrunch from a posted link

https://techcrunch.com/2024/07/24/crowdstrike-offers-a-10-apology-gift-card-to-say-sorry-for-outage/

and after some reading couldn't exit it at all tapping both my back key and the back arrow on the top.

Due to how inconvenient the arrow on top is, I suggest to make it the exit button that closes the browser and returns user to Lemmy at once, while usual back buttons keep acting like they are now.
