How does one access UK biobank genotype information via patient ID?

I have extracted SNPs from a gene of interest using PLINK in .bgen+.sample file formats, and now I'd like to be able to view genotype by patient ID (eid), or in some other way, so that I can see if there is any association with their genotype (using the extracted SNPs) and a disease (I have the corresponding patient ID's for the disease cohort, so I'd just like to match that up with their genotype).
