Lol no. That's not how it works. Many have the issue (including myself) of it being impossible to use files due to Phone, Android version, data carrier, or all 3. On my Note 20 Ultra running Android 12 with AT&T its not possible due to Samsung Knox and ATT security features, any Samsung S series phone with Knox (if you have it it'll say during boot) isn't capable of doing it, while my Galaxy A11 running Android 11 without Knox from T-Mobile can. It's not as simple as "LeArn how tO dO iT dOnT bE lAzY"
Samsung Knox isn't usually active, it's mainly geared towards enterprise users who need the extra protection.
You have my sympathy for being in that position + carrier "features" (not common except in the USA), but honestly you're the first that I've come across...
I borrowed a clean (no lockout, no Knox) S21+ running Android 12, the default file manager was indeed locked down, but a different file manager such as Solid Explorer or
one of the others here can indeed access Android\Data, you just need to grant it permission. And that seems to cover 99% of potential visitors from around the globe... Indeed, the person above that I gave the video to has now posted a blueprint.txt file on another thread, so it seems to have worked for them.
