WVD scaling tool built on Logic Apps and Azure automation

Roop_Kiran_Chevuri I been using the WVD on my LAB and it works well,  but just wandering if there any other trigger that we could use using a users is logging in,  as my one scenario that I have difficulties is that starting the peak time and there are simultaneous login VM starting took time.  So user is cramping on only one machine in the beginning.   Sorry for the question just a noob on Logic APP and its capabilities just trying to expand my knowledge if Automation and Logic APP can handle this.  Thank you.
