Please what if my boss writes a letter stating that he is sponsoring my education or a letter saying he gave me a scholarship and he would be sponsoring my studies, does he still needs to find the block acct, just trying to know if individuals can write saying they granted me scholarship, in that case, what’s the needed documents to backup the claim

Kindly help me with further explanation on the block account issue, I just got an admissions letter from a Germany university, I have been online checking on the needed things to do, and I saw this block acct stuff, since it’s my place of work that is sponsoring my stay and academics in Germany, and they will be sending the bank statement as an evidence ( more or less like a scholarship by my boss) do I still need to open an block acct, sincere opinion please
