Yes, people and organizations have come forward and said they have evidence. It's a simple google search away. You, similar to the OP, seem to be ignoring all of the many warnings from many organizations. If you think that intelligence agencies are going to show you, a random person, or the public the evidence directly I think you're not really aware of how they work. Why would they burn assets and methods to prove this when everyone agrees on it?

I would probably agree with you that attaining evidence of this spying would be somewhat easier for governments than for others. However, the rest of your assertion that these accusations are only due to geopolitics is pretty out there given it's almost universal at this point that people think Huawei are not on the up and up.

Hurtling accusations without any sort of supporting evidence is literally what you've just done. There's a ton of evidence out there to not use them.

Here are some pieces of evidence for you that literally were on page 1 and 2 of a search:

CIA, NSA, FBI just last year saying the US shouldn't use them: https://www.forbes.com/sites/marcochiappetta/2018/11/25/u-s-...

At least the US and Australian Intelligence services have hard evidence of them spying for the Chinese government: https://www.axios.com/report-australian-intelligence-know-hu... https://www.reuters.com/article/us-huawei-security/former-ci...
