@archieraptor Swings and pushups can be more than enough to start with. Either 2 handed or hand-to-hand or switch sides every set/every 5 reps.
Set a timer to beep every 1.5min, do 10 swings, rest, do 10 pushups when it beeps again, rest. That's a 3 mins long set, repeat for as much as you need (10 sets = 30 minutes, 100 swings, 100 pushups)
"Iron Cardio" is a chain of 1 clean, 1 press, 1 squat, rest, repeat on the other side. Has plenty of variations (add a rep on the press one day 1c2p1sq and on the squat another day 1c1p2sq). Set a timer for 20-30-40 mins and do as many sets as possible with adequate rest
"Swing Swing Other Thing" where you do 10 swings on minute one, 10 swings on minute two, something else on minute three, repeat for 30' (200 swings + X reps of whatever you chose to be your other thing)
"SFG Plan A" (they have an article about it on their blog) has you start with 1clean+jerk every 30'" alternating left and right side and work up to 30' before you add a second clean then a second jerk etc till you can do 3c+j every 30'' alternating arms. You can use the push press to hone technique.
"Humane burpee" is one of my favourite: 15 swings, 5 goblet squats, 3 pushups. Repeat. 5 rounds = 75swings, 25 goblets, 15 pushups. Change/scale accordingly.
As you see, there are plenty of options for you to play with, as you say you are fairly new to kbs, I'd try to build up a bit of technique (=confidence) with cleans, presses, squats, swings, before snatching/jerking
