Can I use the unstandardised latent variable scores as they are provided in the IPMA for hypothesis testing (t-test)?

Hello everyone,
hope you can help me with this as I am stuck in my data analysis.
I know I can obtain unstandardized latent variable scores from the IPMA. I also read online lots of articles discussing Hypothesis testing through the latent factor scores. My questions are:
I need to carry out a t-test to test differences between two latent variables of two different groups. Can I use the Latent variable scores as they are provided by the IPMA for each observation or do I need to compute any sort of adjustment? Meaning, can I copy and paste those LVS in SPSS for all the observation and then carry out my T-test? Although I read several posts and articles on the matter I could not find any clear indication on whether I could simply copy and paste those scores or whether I need to adjust them for the number of items etc.
Also, providing that I am comparing two different groups form two different population, would be good to check first for measurement invariance?
Hope you can help me with the above cause I am really stuck and do not know how to proceed further.
Thank you!
