Launchpad pro MKII & MKII Functionalities

Hi all ! i would like to understand the features that both Launchpads (MKII and MKIII) have with touchdesigner.

in the mkIII version you can create custom components (sliders, sequencers etc with the novation component tool online)… so i wonder, can components like faders be read as such in touch designer ?

meanwhile, in the MKII version, since there is no custom component tool online, although possible to create faders differently, can these be read as such in TD ? or will they just be read as buttons ?
