Are you sure Suricata is forwarding logs to Wazuh? It’s been a little while since I’ve used the tools but generally with detections there are 3 possible issues. Telemetry- Are you receiving the logs in the correct location? Taxonomy- Are the logs correctly tagged and processed. Logic- is the rule logic correct

You mentioned a successful login... To what service? If I understand your question, you haven't written the rule? Here's an example rule for SSH:
alert tcp any any -> any 22 (msg:"Failed SSH Login Attempt"; flow:to_server,established; content:"SSH-"; depth:4; content:"Failed password"; nocase; classtype:attempted-recon; sid:1000001; rev:1;)
alert tcp any any -> any 22 (msg:"Failed SSH Login Attempt"; flow:to_server,established; content:"SSH-"; depth:4; content:"Failed password"; nocase; classtype:attempted-recon; sid:1000001; rev:1;)
Without more details it's hard to assertain where your problem lies. Like E-Man suggested, it could be an issue at any point of the process. To fix it, you need to verify every link of the "chain."
