I’m not familiar with this particular model, you need to look for a whole of some sort. Cable is inserted in certain lever position, so look for any holes and keep watching it while you rotate the shifter back and forth. The whole with signs of rust might be the one

I swear some of thess are designed to not be serviceable. They just click together and are made of brittle plastic. YOu can try to squeeze the tabs on the inside of the small end and force it apart, but you might end up breaking it.
I’ve worked on bikes for charity purposes and we run into stuff like this all the time. Cheap department store bikes that they don’t expect to last long enough or ridden enought that you would need to replace the shift cable
RJ The Bike Guy has a video on how to replace the cable on grip shifters.
Double check with the manufacturer specs for your particular shifter before you try to pull it apart so you don’t break the shifter.
Be careful not to break any of the plastic tabs on the shifter internals when disassembling. Also, be careful not to lose the small spring clip.
I despise grip shifters – they can be difficult to work with without breaking them.
Good luck.

Don’t bother. They are shit. A sram 7 or 8 speed thumb shifter is about ten quid on Amazon. You can buy a rubber single to make the upshifter longer for kids weedy thumbs.

I changed the cable on one of these exact shifters the other day at the shop (bike mechanic). They are awful, but it’s possible. The shifter pulls apart but you need to look in the narrow end and you will see 2 large plastic tabs opposite each other. Both of those need to be gently lifted up towards the centre of the hole through the middle. The plastic is very cheap quality and I have broken one of the tabs in the past trying to disassemble these. Once you have the two tabs lifted you will be able to gently pull the larger piece away from the narrow part. Pull it apart very slowly and gently so you don’t disturb the internals too much and you should be able to see the head of the cable and wiggle it free and thread the new one in. There’s not much to them inside but there is a weird long spring and a small metal clip which is sprung (that is the part which actually indexes and makes it click). Even if you pull it apart too much and it all falls apart, you should be able to figure out how everything goes back together but my advice would be to go slow and even better, take a video of yourself doing it close up so if it does go wrong, you can review the video and maybe see where the bits came from. The long spring locates onto two little plastic bumps though whic.h you will see if you take it apart that far

There are two tabs that are expanded and keep the twist shift piece in place. This is viewable by staring at the shifter from the twist end not the insert end.
Grab some needle nose pliers to squeeze the two inner tabs and the twister part should slide away from the body.
Be mindful of the metal clip inside the mechanism that locks the shifts into place. Plenty of video on how to orient that clip to put in place.
Yes there are ‘better’ shifters but that info is not helpful for the task at hand.
