If you want to complete the Higg FSLM (self-assessment only), you do not need to create a Gateway account. If you want to have your FSLM self-assessment verified and obtain a verified assessment report (in other words, if you want vFSLM), you do need to create an account on the Gateway.
Note 1: only verified assessment data can be shared (no self/joint-assessment data)
Note 2: facilities can only register on the Gateway when SLCP has launched in their countries/regions
