Gitlab cicd pipeline trigger using technical user

Hello Gitlab team,

I want to implement solution where CICD pipeline should trigger from technical user once developer merges a code. It is not triggered from developer as soon as he merges a code. when he will merge a code, CICD trigger control will go to technical user(non existent user) and CICD pipeline will trigger on his gitlab instance.

Please let me know urgently, is this functionality feasible in gitlab? If yes, how can it be achievable. Please help me on this… It is very impaortant for me. Please suggest any solution on this today only.
