Mikrotik POE-Out to power an IP phone

Hey, I'm wondering if it is possible to make my Routerboard's POE-Out (passive POE output) power an IP phone which only supports a normal DC input and 802.3af.

I searched a bit and found an adapter but I'm not sure if it supports Mikrotik's way of doing it, as they seem to be able to support 1Gbps along with power on one cable: https://www.amazon.fr/Injecteur-Adaptateur-Alimentation-Synth%C3%A9tiseur-S%C3%A9parateur/dp/B07TWL9F3H/ref=mp_s_a_1_1

Also seen Ubiquiti's 802.3af to passive POE converter, but it unfortunately only seems to support that direction.

Thanks in advance (and sorry if this is the wrong sub for this, please point me out to a better one if you know any!)
