I want to implement writing of data on password-protected NFC 25 tag) ST25DV04K

In my case, I have enabled write protection on Area1 with password 1 set using the NFC tap App.

I want to use a known password to enable my Android and iOS to write the data on these tags.

Could you please point ot to the example or resources to implement this feature?
