place the digitizer on a clean surface in front of you. Note that the inner touch side also has a clear protective film on it. Gently bend the area around the connection tapes (so as not to stick the tape to the foil but to the proper screen)

remove the tape protecting the adhesive on the tapes from the inside. This side should stick to the digitizer glass.

gently bend the tape to the surface of the digitizer. The glue is not very strong but should be enough for a moment. Cover the glued tape with the previously removed digitizer protective film (in the previous point). This will stop the tape from peeling off

do not press the adhesive tape. The concentrated connection paths of the entire digitizer in this place are less than 1mm. It's a really delicate and sensitive place. Pressing (possibly breaking) may cause dead lines on the touch surface (after all, it worked during the previous test :-) )
