How to flash aptX codec

Hi all,

I’d like to flash the aptX codec on my FP3 but I don’t know how I should proceed.
Is it possible to flash it when /e/ is already installed or do I have to flash it at the same time than the first /e/ flashing ?

Has anyone already tried it or flash it ?

I’d like to flash /e/ and aptx codec just after but I don’t know if it is possible to do it or if their is a risk to brick m’y FP3. Any advise ? Shoud I try or not at all ?
