Depending on how complicated your passwords usually are and how many GPUs you have access to, you might be able to brute force it using hashcat or johntheripper, I think btcrecover might be able to crack electrum wallet passwords as well. I also see someone supposedly wrote a python script over GitHub called pwscanx.
None of these are going to have a simple guide, it's going to rely on you doing the work to get familiar with the tools, or paying someone who already has the knowledge to do it for you. Even then if you used a sufficiently complex password, it may be impossible.
