squeaking noise / chirping noise when driving

[oDx_Vortex]

i have been driving a lot for the past couple of weeks and there was a slight squeaking noise/ chirping noise.
i ignored it as i thought it might be something in the boot because it sounded like it was int the car or just outside the car. here's a link to a video with the exactly same sounding noise

my car makes the sound without hitting a bump
i tried to find a solution but everyone has been telling me different things so i thought i will try here as i always get a good response. i had a mot in January and it passed but the advisory's was

• Nearside Rear Axle swivel pins and bushes swivel pin and/or bush slightly worn (5.1.2 (b) (i))
• Offside Rear Axle swivel pins and bushes swivel pin and/or bush slightly worn (5.1.2 (b) (i))

I struggle to find parts for this as i dont know which one to buy. seat leon fr 2017 5f 1.4tsfi
but again i dont want to try it and get it wrong and it still makes a noise
so i need help with:
ideas to fix it
the correct part to fix the bushes and a video if possible to help with the repair

Many thanks
