Will my mums Golden Visa be revoked?

Hi Everyone

my mum has a golden visa and she is a housewife living by herself in the country. she got it via my sisters university scores. both me and my sister are working abroad and due to the current ongoing situation , we are quite nervous.

my mums friend is saying since she is unemployed and is on golden visa - her visa will be revoked if she leaves the country for sometime.

we are indians - is this a possibility?

anyone in immigration - could you kindly clarify ? I send my mum money monthly for all her expenses and upkeep and visit the country often.

thank you in advance for your help.
