Finding corresponding Sentinel-2 data available through AWS

I have a Sentinel-2 data ID as : S2B_MSIL2A_20201006T052709_N0214_R105_T43PCT_20201006T075133.zip

Now, I wish to download the data with the ID as mentioned above from AWS, I went through the naming convention mentioned over here https://roda.sentinel-hub.com/sentinel-s2-l2a/readme.html , but unable to comprehend how this can be done. I have two questions :

a) How can I download the data from AWS with above ID ?
b) I want to download the whole data as a zip file (not each file separately) ? Please suggest.
