Your description is unclear to me unfortunately:
You already can do the following:

1. Add OCGs (Optional Content Groups) with a desired name like "image" or "text"
2. Insert vector graphics, text and images referring to an OCG / OCMD.
3. Attach existing OCGs to existing images.

What do you need that is not covered by the above?

###for text extarct and text layer i am using this
import sys, fitz
fname = '/home/satvir/Downloads/T0-00---TITLE-SHEET-&-NOTES-2023-04-15-03-31-08-473_67_1.pdf'
doc = fitz.open(fname) # open document
import fitz
page = doc[0]
ndoc = fitz.open()
npage = ndoc.new_page(width=page.rect.width, height=page.rect.height)
text_layer = ndoc.add_ocg("Text Layer")
extra_flags = fitz.TEXT_PRESERVE_LIGATURES | fitz.TEXT_PRESERVE_WHITESPACE
blocks = page.get_text("rawdict")["blocks"]
helv = fitz.Font("helv")
for b in blocks:
if "lines" not in b:
continue
for l in b["lines"]:
cos, sin = l["dir"]
matrix = fitz.Matrix(cos, -sin, sin, cos, 0, 0)
for s in l["spans"]:
textBox = s['bbox']
fsize = s["size"]
font = s["font"]
for c in s["chars"]:
# print(font)
# if font.lower().startswith("arial"):
# font = arial
# else:
# font = helv
ch = c["c"]
origin = fitz.Point(c["origin"])
tw = fitz.TextWriter(page.rect)
# tw.append(origin, ch,font=font, fontsize=fsize)
tw.append(origin, ch, fontsize=fsize)
tw.write_text(npage, morph=(origin, matrix),oc=text_layer)
npage.clean_contents() # recommended
ndoc.subset_fonts() # recommended
ndoc.ez_save("/home/satvir/Downloads/text_layer.pdf", garbage=4)
