Is this native code possible for further static analysis?

Question

I was trying to reverse engineer a native lib code in an android app. the .so contains many functions. But the function sUQWWyTBEs() was referred in the Java code. I was curious how this function works, the code of the function sUQWWyTBEs() decompiled with Ghidra:

*************************************************************
                             *                           FUNCTION                          
                             *************************************************************
                             undefined  __cdecl  Myapp_sUQWWyTBEs()
             undefined         w0:1           <RETURN>
             longlong *        x0:8           param_1
                             Myapp_sUQWWyTBEs XREF[2]:     Entry Point (*) , 00101350   
        00100e44 08  00  40  f9    ldr        x8, [param_1 ]
        00100e48 01  00  00  b0    adrp       x1, s_c7a584936712f32773d3d0a_00101000           ; = "c7a584936712f32773d3d0a"
        00100e4c 21  60  08  91    add        x1, x1, #0x218
        00100e50 02  9d  42  f9    ldr        x2, [x8, #0x538 ]
        00100e54 40  00  1f  d6    br         x2

in my understanding, I have made the static analysis as like following:

00100e44 08 00 40 f9 ldr x8, [param_1 ]

load the value at memory address param_1 into register x8.

0100e48 01 00 00 b0 adrp x1, s_c7a584936712f32773d3d0a_00101000

sets register x1 to 0x101000.

00100e4c 21 60 08 91 add x1, x1, #0x218

adds 0x218 to x1, so it sets x1 to 0x101218.

00100e50 02 9d 42 f9 ldr x2, [x8, #0x538 ]

loads the value at x8 + 0x538 into x2.

00100e54 40 00 1f d6 br x2

and finally branches to the address stored in x2.

with that being said, Here I don't know the memory at address at x2, obviously it initially depends on the value param_1 holds. is there way or how can I refer where param_1 was initialized? I don't know very much about usage of Ghidra or other reverse engineering tools. any one might help would be appreciated.

Edit: This function returns a string like this 47fjlkj843h9asjklj94kljfsad93j4l2715943hasd... but what I wanted is that how this value was generated or returned.
