Implement the suggested improved fit measures ( robust RMSEA & CFI as well as mean-and-variance corrected chi-square and t-size measures)
Describe alternatives that you have considered

Additional context
Current guidelines suggest that robust fit indices should be considered for inclusion in JASP as part of confirmatory factor analysis
