Do reverts really need to say the shahadah in arabic?

Islamqa.info tells the shahadah can be ***affirmed in its meaning***. https://www.google.com/amp/s/islamqa.info/amp/en/answers/239026 The following are instances in Quran & sunni corpus where people attained Islam with a testimony which is different to the standard one. 1. The magicians of firaun said ***"We believe in the Rabb of Musa and harun"*** Quran 20:70 2. The people of ditch, ashabul aqdood said ***"We believe in the Rabb of this young man"*** [Muslim 3005] 3. Zaid bin amr bin nufayl said ***"O Allah bear witness I'm upon the religion of Ibrahim "*** [Bukhari 3827] 4. Waraqah bin nawfal affirmed that the angel which brought revelation to prophet is called namoos and ***he would support him if he was alive in future*** [bukhari 3392] There is ijma that all above became muslims and waraqah became a companion by that statement of his as per some scholarly opinions. https://islamqa.info/en/answers/182441/was-waraqah-ibn-nawfal-a-companion Since the magicians of firaun didnt speak Arabic, it can be construed that they said the testimony with a identical wording in a different language. So the question is can reverts whose language is not Arabic can say something similar to ***"I believe in deity of muhammad"*** or ***"I believe in deity of muslims"*** to validate to muslims that they follow Islam now? PS: it will ease difficulty of non Arabic speaking reverts, to say the testimony, since Islam is easy [ bukhari 39]
