that second from top fuse tap seems like it should work on the amazon listing, maybe it just needs a little finesse?
this might also be of use if you cant get that working.

edit: i recall doing this on another car before, i ended up using one of the provided fuses with the same value on the fuse tap and not the original fuse.
Garmin Constant Power Cable,... https://www.amazon.com/dp/B094Y3KNFJ?ref=ppx_pop_mob_ap_share
I use this constant power cable and haven’t had any issues in my 3 months of ownership. I don’t know Tundra interiors well but I had no problem hiding the cable in my sedan.
Power on either only with car on, for 24 hours, or indefinitely, without having to tap a fuse. While this is Garmin, there are others and any should work. I use this for one of my cars, but my Subaru has the camera plugged into glovebox.
