Sole director / employee UK limited company cash reserves, any sensible long-term investment approaches / ideas?

Hi all, wondering if anyone has advice what to do with sole director / employee UK Ltd company funds just sitting in bank losing money to interest... Ltd company holding EUR / USD but has nothing to do with finance, our AI friend suggests:

Order of buying from here:

1. CNDX
2. US Treasury Bills
3. VWRA
4. XEON

• ~40% safe assets (T-bills + XEON)
• ~50% equities (VWRA + CNDX)
• ~10% business cash buffer

Hopefully someone else has similar experience, not an investment chap, just wanted to make idle cash work a little rather than staying stagnant and losing power.
