FUSE Box Labels (2 in Engine Bay; 1 in the Interior)

[AnchoredInTruth]

First post. Purchased a 2025 RX 350h Eminent White/Peppercorn Luxury with Tech / Convenience / Towing Kit two weeks ago.  Focusing in on purchasing a Front/Inside Dashcam (Vantrue N2X?)  How does the owner get hold of the Fuse Box Diagram showing Fuse / Amps / Purpose?  Used to get these in the Manual but, not Lexus!  In particular, looking for the Fuse information for the Interior Fuse Box typically under the Driver's footwell.  I would imagine each Trim has different fuse box diagram for the different technologies in each trim i.e., head's up display in mine.  In any event, any help would be appreciated if anyone has installed a dashcam and Fuse Tapped in the correct fuse location.  I would imagine that the Experts in the Service Department would have a "secret" manual for these types of requirements given all the Lexus model trims.
