She's not ready.
Keep in mind, that for the 1st year of life, breastmilk/Formula is a baby's PRIMARY source of nutrition... NOT solids and NOT other liquids.
This is per our Pediatrician as well.
A baby... can TOTALLY survive AND flourish, just on breastmilk or Formula, for the 1st year. Even longer.
Solids at this age, is only an introduction. And for the 1st year. It is NOT their main 'meal' nor their main intake. NOR do babies this age, eat 3 times a day as adults do. It has to be gradually... built up... so their systems can also adjust. Over the course of a year even.
Your baby also still has her 'tongue reflex' whereby they DO push foods out of their mouth. This is an indication, that she is not ready for solids, yet.

If you force solids and she is not ready, developmentally or biologically... it will not be good for her. The internal organs, also has to develop too, still and her mouth reflexes.
Your baby is so young. Its fine.
Don't start food battles yet... because, throughout childhood, food eating in kids... REALLY vary and it is normal. If you get frustrated about it now... and later... then the child will too. And then they won't enjoy meal times.
Go by her cues.
all the best,
