[US] Anyone with an experience of applying for a second STEM OPT? : immigration

I’ve checked the USCIS web page and it says that for every diploma in a STEM program from affiliated faculties one is eligible to use for STEM OPT.

I arrived in 2013 for a PhD program and in 2015 accomplished the necessities for a Masters [with Thesis n publications]. I continued with the identical program however switched professors and analysis area and accomplished my PhD in 2019. I’m at the moment within the final 12 months of my STEM OPT(PhD) and was questioning if I can get a second STEM OPT for my masters.

Any info on this regard is way appreciated.
