Could be one of many issues..
#1 the o-ring at the base of the reservoir where it connects to the power steering pump
#2 the reservoir or power steering pump may be leaking externally (cracked reservoir or leaking from pump front seal
#3 the lines at the power steering cooler (radiator)
#4 some of the seals on the power steering rack
#5 internal seals of the power steering rack
pretty much any part of it can and will leak given enough time. You need to see where the leak is and start from the top and work your way down incase there are multiple issues with your system.

Did you get the metal clip back on and everything bolted back down properly? Do you have a small mirror and flashlight to check the area of that o-ring to see whether it is that or the underside of the reservoir?
Don't go with common parts failures. Clean things up and figure out what your vehicle needs before throwing money away and replacing parts you may not need to.

Regarding item 3 above: how do I go about changing these lines. I might have a leak, but it’s not dripping at all. See pic: thank you,
Seeping between the rubber in between the line, this was taken under the car up. Hope it’s the correct oil cooler line that hooks to the radiator. Thanks

Yes, the line with the grommets is the return line.
Below are the part numbers that you should get, including at least one grommet.
Purchase the line first and then see what metric size wrench fits on the nut. Then borrow or purchase the corresponding metric Flare Nut Wrench to loosen and tighten the line nut.
Additionally, after parts replacement, DO NOT START ENG. You must bleed the system first.
