KP2android offline, *.pdf - File attachment cannot be opened or can only be opened via a detour ?

What version of Keepass2Android are you using?
Keepass2android offline, Ver.1.09e-r7 (also tested online version) - Android13

x.kdbx file works perfectly on Android8 (same Keepass Ver. as Android13), all file attachments can be opened with the "Office Documents Viewer".

Same x.kdbx on Android13 can open *.txt in the "Totalcmd-Editor";
*.jpg can be opened via (3 points: open with) "Show photos" (system app) - not with e.g. "QuickpicGalleryPro"

Problem: "*.pdf" cannot be opened - #App has no authorization# (e.g. I cannot grant this authorization to "Office Documents Viewer" - system does not allow it)

Question: which app is able or how can I open file attachments "*.pdf" offline in Keepass2Android?

Please let me know if this is no longer possible so that I don't test all possible apps for nothing.

Thank you, Greetings from Tirol

Start by reproducing the PDF attachment behavior on Android 13 with the reported Keepass2Android versions, then compare it with Android 8 and the working TXT and JPG attachments. Done means identifying whether a compatible viewer can open the PDF offline or documenting that Android 13 no longer permits this flow.
