How do I add Okt to MetaMask?

Could you please elaborate on the process of adding Okt to MetaMask? I'm a bit new to this and would appreciate a step-by-step guide. Are there any prerequisites I need to fulfill before I can proceed? Also, is there a specific version of MetaMask that's recommended for adding Okt, or does it work with all versions? I'd like to ensure that I'm doing this correctly and securely. Thank you in advance for your help.
