What would Christians sympathetic to Holy Spirit 'speaking in tongues' today say about such a practice going on in non-Christian religions?

I found this claim in a Protestant Christian web-site (which prompts this question): "In just about every part of the world, glossolalia can be observed. Pagan religions all over the world are obsessed with tongues. These include the Shamans in the Sudan, the Shango cult of the West Coast of Africa, the Zor cult of Ethiopia, the Voodoo cult in Haiti, and the Aborigines of South America and Australia. Murmuring or speaking gibberish that is construed to be deep mystical insight by holy men is an ancient practice." Glossolalia is the term for what is more usually called 'speaking in tongues' as practiced in some charismatic / pentecostal denominations. The quote came from https://www.gotquestions.org/glossolalia.html but there was nothing more about the non-Christian practice, because the page was out to present a biblical view. It was just that claim that I wanted to ask about, preferably getting answers from Christians sympathetic to what they view as modern-day Holy Spirit speaking in tongues. Would they readily admit to that non-Christian (and, therefore, non-Holy Spirit) phenomenon? Or would they deny such a thing went on in non-Christian religions? (Which is NOT to invite arguments for their practice being authentic while non-Christian practices were a sham.) I'm not asking for theological explanations about glossolalia but **whether it goes on in non-Christian circles and, therefore, whether that presents a challenge to Christians sympathetic to its practice in their ranks, or not.**
